Chapter 2 - Formation and Authority of Agents
46
Section 1 - Formation
47
2.1.1
Article 2.1.1 - Manner of formation
48
A contract may be concluded either by the acceptance of an offer or by conduct of the parties that is sufficient to show agreement.
49
2.1.2
Article 2.1.2 - Definition of offer
50
A proposal for concluding a contract constitutes an offer if it is sufficiently definite and indicates the intention of the offeror to be bound in case of acceptance.
51
2.1.3
Article 2.1.3 - Withdrawal of offer
52
(1) An offer becomes effective when it reaches the offeree.
53
(2) An offer, even if it is irrevocable, may be withdrawn if the withdrawal reaches the offeree before or at the same time as the offer.
54
2.1.4
Article 2.1.4 - Revocation of offer
55
(1) Until a contract is concluded an offer may be revoked if the revocation reaches the offeree before it has dispatched an acceptance.
56
(2) However, an offer cannot be revoked
57
(a) if it indicates, whether by stating a fixed time for acceptance or otherwise, that it is irrevocable; or
58
(b) if it was reasonable for the offeree to rely on the offer as being irrevocable and the offeree has acted in reliance on the offer.
59
2.1.5
Article 2.1.5 - Rejection of offer
60
An offer is terminated when a rejection reaches the offeror.
61
2.1.6
Article 2.1.6 - Mode of acceptance
62
(1) A statement made by or other conduct of the offeree indicating assent to an offer is an acceptance. Silence or inactivity does not in itself amount to acceptance.
63
(2) An acceptance of an offer becomes effective when the indication of assent reaches the offeror.
64
(3) However, if, by virtue of the offer or as a result of practices which the parties have established between themselves or of usage, the offeree may indicate assent by performing an act without notice to the offeror, the acceptance is effective when the act is performed.
65
2.1.7
Article 2.1.7 - Time of acceptance
66
An offer must be accepted within the time the offeror has fixed or, if no time is fixed, within a reasonable time having regard to the circumstances, including the rapidity of the means of communication employed by the offeror. An oral offer must be accepted immediately unless the circumstances indicate otherwise.
67
2.1.8
Article 2.1.8 - Acceptance within a fixed period of time
68
A period of acceptance fixed by the offeror begins to run from the time that the offer is dispatched. A time indicated in the offer is deemed to be the time of dispatch unless the circumstances indicate otherwise.
69
2.1.9
Article 2.1.9 - Late acceptance. Delay in transmission
70
(1) A late acceptance is nevertheless effective as an acceptance if without undue delay the offeror so informs the offeree or gives notice to that effect.
71
(2) If a communication containing a late acceptance shows that it has been sent in such circumstances that if its transmission had been normal it would have reached the offeror in due time, the late acceptance is effective as an acceptance unless, without undue delay, the offeror informs the offeree that it considers the offer as having lapsed.
72
2.1.10
Article 2.1.10 - Withdrawal of acceptance
73
An acceptance may be withdrawn if the withdrawal reaches the offeror before or at the same time as the acceptance would have become effective.
74
2.1.11
Article 2.1.11 - Modified acceptance
75
(1) A reply to an offer which purports to be an acceptance but contains additions, limitations or other modifications is a rejection of the offer and constitutes a counteroffer.
76
(2) However, a reply to an offer which purports to be an acceptance but contains additional or different terms which do not materially alter the terms of the offer constitutes an acceptance, unless the offeror, without undue delay, objects to the discrepancy. If the offeror does not object, the terms of the contract are the terms of the offer with the modifications contained in the acceptance.
77
2.1.12
Article 2.1.12 - Writings in confirmation
78
If a writing which is sent within a reasonable time after the conclusion of the contract and which purports to be a confirmation of the contract contains additional or different terms, such terms become part of the contract, unless they materially alter the contract or the recipient, without undue delay, objects to the discrepancy.
79
2.1.13
Article 2.1.13 - Conclusion of contract dependent on agreement on specific matters or in a particular form
80
Where in the course of negotiations one of the parties insists that the contract is not concluded until there is agreement on specific matters or in a particular form, no contract is concluded before agreement is reached on those matters or in that form.
81
2.1.14
Article 2.1.14 - Contract with terms deliberately left open
82
(1) If the parties intend to conclude a contract, the fact that they intentionally leave a term to be agreed upon in further negotiations or to be determined by a third person does not prevent a contract from coming into existence.
83
(2) The existence of the contract is not affected by the fact that subsequently
84
(a) the parties reach no agreement on the term; or
85
(b) the third person does not determine the term, provided that there is an alternative means of rendering the term definite that is reasonable in the circumstances, having regard to the intention of the parties.
86
2.1.15
Article 2.1.15 - Negotiations in bad faith
87
(1) A party is free to negotiate and is not liable for failure to reach an agreement.
88
(2) However, a party who negotiates or breaks off negotiations in bad faith is liable for the losses caused to the other party.
89
(3) It is bad faith, in particular, for a party to enter into or continue negotiations when intending not to reach an agreement with the other party.
90
2.1.16
Article 2.1.16 - Duty of confidentiality
91
Where information is given as confidential by one party in the course of negotiations, the other party is under a duty not to disclose that information or to use it improperly for its own purposes, whether or not a contract is subsequently concluded. Where appropriate, the remedy for breach of that duty may include compensation based on the benefit received by the other party.
92
2.1.17
Article 2.1.17 - Merger clauses
93
A contract in writing which contains a clause indicating that the writing completely embodies the terms on which the parties have agreed cannot be contradicted or supplemented by evidence of prior statements or agreements. However, such statements or agreements may be used to interpret the writing.
94
2.1.18
Article 2.1.18 - Modification in a particular form
95
A contract in writing which contains a clause requiring any modification or termination by agreement to be in a particular form may not be otherwise modified or terminated. However, a party may be precluded by its conduct from asserting such a clause to the extent that the other party has reasonably acted in reliance on that conduct.
96
2.1.19
Article 2.1.19 - Contracting under standard terms
97
(1) Where one party or both parties use standard terms in concluding a contract, the general rules on formation apply, subject to Articles 2.1.20 2.1.22.
98
(2) Standard terms are provisions which are prepared in advance for general and repeated use by one party and which are actually used without negotiation with the other party.
99
2.1.20
Article 2.1.20 - Surprising terms
100
(1) No term contained in standard terms which is of such a character that the other party could not reasonably have expected it, is effective unless it has been expressly accepted by that party.
101
(2) In determining whether a term is of such a character regard shall be had to its content, language and presentation.
102
2.1.21
Article 2.1.21 - Conflict between standard terms and nonstandard terms
103
In case of conflict between a standard term and a term which is not a standard term the latter prevails.
104
2.1.22
Article 2.1.22 - Battle of forms
105
Where both parties use standard terms and reach agreement except on those terms, a contract is concluded on the basis of the agreed terms and of any standard terms which are common in substance unless one party clearly indicates in advance, or later and without undue delay informs the other party, that it does not intend to be bound by such a contract.
106
Section 2 - Authority of Agents
107
2.2.1
Article 2.2.1 - Scope of the Section
108
(1) This Section governs the authority of a person ("the agent"), to affect the legal relations of another person ("the principal"), by or with respect to a contract with a third party, whether the agent acts in its own name or in that of the principal.
109
(2) It governs only the relations between the principal or the agent on the one hand, and the third party on the other.
110
(3) It does not govern an agent's authority conferred by law or the authority of an agent appointed by a public or judicial authority.
111
2.2.2
Article 2.2.2 - Establishment and scope of the authority of the agent
112
(1) The principal's grant of authority to an agent may be express or implied.
113
(2) The agent has authority to perform all acts necessary in the circumstances to achieve the purposes for which the authority was granted.
114
2.2.3
Article 2.2.3 - Agency disclosed
115
(1) Where an agent acts within the scope of its authority and the third party knew or ought to have known that the agent was acting as an agent, the acts of the agent shall directly affect the legal relations between the principal and the third party and no legal relation is created between the agent and the third party.
116
(2) However, the acts of the agent shall affect only the relations between the agent and the third party, where the agent with the consent of the principal undertakes to become the party to the contract.
117
2.2.4
Article 2.2.4 - Agency undisclosed
118
(1) Where an agent acts within the scope of its authority and the third party neither knew nor ought to have known that the agent was acting as an agent, the acts of the agent shall affect only the relations between the agent and the third party.
119
(2) However, where such an agent, when contracting with the third party on behalf of a business, represents itself to be the owner of that business, the third party, upon discovery of the real owner of the business, may exercise also against the latter the rights it has against the agent.
120
2.2.5
Article 2.2.5 - Agent acting without or exceeding its authority
121
(1) Where an agent acts without authority or exceeds its authority, its acts do not affect the legal relations between the principal and the third party.
122
(2) However, where the principal causes the third party reasonably to believe that the agent has authority to act on behalf of the principal and that the agent is acting within the scope of that authority, the principal may not invoke against the third party the lack of authority of the agent.
123
2.2.6
Article 2.2.6 - Liability of agent acting without or exceeding its authority
124
(1) An agent that acts without authority or exceeds its authority is, failing ratification by the principal, liable for damages that will place the third party in the same position as if the agent had acted with authority and not exceeded its authority.
125
(2) However, the agent is not liable if the third party knew or ought to have known that the agent had no authority or was exceeding its authority.
126
2.2.7
Article 2.2.7 - Conflict of interests
127
(1) If a contract concluded by an agent involves the agent in a conflict of interests with the principal of which the third party knew or ought to have known, the principal may avoid the contract. The right to avoid is subject to Articles 3.12 and 3.14 to 3.17.
128
(2) However, the principal may not avoid the contract
129
(a) if the principal had consented to, or knew or ought to have known of, the agent's involvement in the conflict of interests; or
130
(b) if the agent had disclosed the conflict of interests to the principal and the latter had not objected within a reasonable time.
131
2.2.8
Article 2.2.8 - Subagency
132
An agent has implied authority to appoint a subagent to perform acts which it is not reasonable to expect the agent to perform itself. The rules of this Section apply to the subagency.
133
2.2.9
Article 2.2.9 - Ratification
134
(1) An act by an agent that acts without authority or exceeds its authority may be ratified by the principal. On ratification the act produces the same effects as if it had initially been carried out with authority.
135
(2) The third party may by notice to the principal specify a reasonable period of time for ratification. If the principal does not ratify within that period of time it can no longer do so.
136
(3) If, at the time of the agent's act, the third party neither knew nor ought to have known of the lack of authority, it may, at any time before ratification, by notice to the principal indicate its refusal to become bound by a ratification.
137
2.2.10
Article 2.2.10 - Termination of authority
138
(1) Termination of authority is not effective in relation to the third party unless the third party knew or ought to have known of it.
139
(2) Notwithstanding the termination of its authority, an agent remains authorised to perform the acts that are necessary to prevent harm to the principal's interests.
140
Chapter 3 - Validity
141
3.1
Article 3.1 - Matters not covered
142

143
(a) lack of capacity;
144
(b) immorality or illegality.
145
3.2
Article 3.2 - Validity of mere agreement
146
A contract is concluded, modified or terminated by the mere agreement of the parties, without any further requirement.
147
3.3
Article 3.3 - Initial impossibility
148
(1) The mere fact that at the time of the conclusion of the contract the performance of the obligation assumed was impossible does not affect the validity of the contract.
149
(2) The mere fact that at the time of the conclusion of the contract a party was not entitled to dispose of the assets to which the contract relates does not affect the validity of the contract.
150
3.4
Article 3.4 - Definition of mistake
151
Mistake is an erroneous assumption relat ing to facts or to law existing when the contract was concluded.
152
3.5
Article 3.5 - Relevant mistake
153
(1) A party may only avoid the contract for mistake if, when the contract was concluded, the mistake was of such importance that a reasonable person in the same situation as the party in error would only have concluded the contract on materially different terms or would not have concluded it at all if the true state of affairs had been known, and
154
(a) the other party made the same mistake, or caused the mistake, or knew or ought to have known of the mistake and it was contrary to reasonable commercial standards of fair dealing to leave the mistaken party in error; or
155
(b) the other party had not at t he time of avoidance reasonably acted in reliance on the contract.
156
(2) However, a party may not avoid the contract if
157
(a) it was grossly negligent in committing the mistake; or
158
(b) the mistake relates to a matter in regard to which the risk of mistake was assumed or, having regard to the circumstances, should be borne by the mistaken party.
159
3.6
Article 3.6 - Error in expression or transmission
160
An error occurring in the expression or transmission of a declaration is considered to be a mistake of the person from whom the declaration emanated.
161
3.7
Article 3.7 - Remedies for nonperformance
162
A party is not entitled to avoid the contract on the ground of mistake if the circumstances on which that party relies afford, or could have afforded, a remedy for nonperformance.
163
3.8
Article 3.8 - Fraud
164
A party may avoid the contract when it has been led to conclude the contract by the other party's fraudulent representation, including language or practices, or fraudulent nondisclosure of circumstances which, according to reasonable commercial standards of fair dealing, the latter party should have disclosed.
165
3.9
Article 3.9 - Threat
166
A party may avoid the contract when it has been led to conclude the contract by the other party's unjustified threat which, having regard to the circumstances, is so imminent and serious as to leave the first party no reasonable alternative. In particular, a threat is unjustified if the act or omission with which a party has been threatened is wrongful in itself, or it is wrongful to use it as a means to obtain the conclusion of the contract.
167
3.10
Article 3.10 - Gross disparity
168
(1) A party may avoid the contract or an individual term of it if, at the time of the conclusion of the contract, the contract or term unjustifiably gave the other party an excessive advantage. Regard is to be had, among other factors, to
169
(a) the fact that the other party has taken unfair advantage of the first party's dependence, economic distress or urgent needs, or of its improvidence, ignorance, inexperience or lack of bargaining skill, and
170
(b) the nature and purpose of the contract.
171
(2) Upon the request of the party entitled to avoidance, a court may adapt the contract or term in order to make it accord with reasonable commercial standards of fair dealing.
172
(3) A court may also adapt the contract or term upon the request of the party receiving notice of avoidance, provided that that party informs the other party of its request promptly after receiving such notice and before the other party has reasonably acted in reliance on it. The provisions of Article 3.13(2) apply accordingly.
173
3.11
Article 3.11 - Third persons
174
(1) Where fraud, threat, gross disparity or a party's mistake is imputable to, or is known or ought to be known by, a third person for whose acts the other party is responsible, the contract may be avoided under the same conditions as if the behaviour or knowledge had been that of the party itself.
175
(2) Where fraud, threat or gross disparity is imputable to a third person for whose acts the other party is not responsible, the contract may be avoided if that party knew or ought to have known of the fraud, threat or disparity, or has not at the time of avoidance reasonably acted in reliance on the contract.
176
3.12
Article 3.12 - Confirmation
177
If the party entitled to avoid the contract expressly or impliedly confirms the contract after the period of time for giving notice of avoidance has begun to run, avoidance of the contract is excluded.
178
3.13
Article 3.13 - Loss of right to avoid
179
(1) If a party is entitled to avoid the contract for mistake but the other party declares itself willing to perform or performs the contract as it was understood by the party entitled to avoidance, the contract is considered to have been concluded as the latter party understood it. The other party must make such a declaration or render such performance promptly after having been informed of the manner in which the party entitled to avoidance had understood the contract and before that party has reasonably acted in reliance on a notice of avoidance.
180
(2) After such a declaration or performance the right to avoidance is lost and any earlier notice of avoidance is ineffective.
181
3.14
Article 3.14 - Notice of avoidance
182
The right of a party to avoid the contract is exercised by notice to the other party.
183
3.15
Article 3.15 - Time limits
184
(1) Notice of avoidance shall be given within a reasonable time, having regard to the circumstances, after the avoiding party knew or could not have been unaware of the relevant facts or became capable of acting freely.
185
(2) Where an individual term of the contract may be avoided by a party under Article 3.10, the period of time for giving notice of avoidance begins to run when that term is asserted by the other party.
186
3.16
Article 3.16 - Partial avoidance
187
Where a ground of avoidance affects only individual terms of the contract, the effect of avoidance is limited to those terms unless, having regard to the circumstances, it is unreasonable to uphold the remaining contract.
188
3.17
Article 3.17 - Retroactive effect of avoidance
189
(1) Avoidance takes effect retroactively.
190
(2) On avoidance either party may claim restitution of whatever it has supplied under the contract or the part of it avoided, provided that it concurrently makes restitution of whatever it has received under the contract or the part of it avoided or, if it cannot make restitution in kind, it makes an allowance for what it has received.
191
3.18
Article 3.18 - Damages
192
Irrespective of whether or not the contract has been avoided, the party who knew or ought to have known of the ground for avoidance is liable for damages so as to put the other party in the same position in which it would have been if it had not concluded the contract.
193
3.19
Article 3.19 - Mandatory character of the provisions
194
The provisions of this Chapter are mandatory, except insofar as they relate to the binding force of mere agreement, initial impossibility or mistake.
