Study Notes
Contractual Obligations and Mistake
- A mistake regarding the nature of contractual obligations is classified as a mistake of law, not a mistake of fact.
- Ignorance of the law is not a valid defense; all parties are presumed to know the law.
- To invoke the legal vitiating factor of mistake, it must be a mistake of fact.
Types of Operative Mistakes
- Three types of legally operative mistakes exist:
- Common or shared mistake
- Mutual mistake
- Unilateral mistake
- Each type can invalidate a contract by disrupting consensus and removing a meeting of the minds.
Common or Shared Mistake
- A common or shared mistake occurs when contractual parties make the same fundamental error.
- Example scenarios include contracting for non-existent items or items that previously existed but do not exist anymore, termed as res extincta.
Legislative Reference
- Goods Act Section 8.1 codifies principles related to common mistakes, stating contracts concerning things that have never existed are void.
- Specific goods must be identified for the contract to be valid under this section; generic terms aren’t sufficient.
Specificity in Contracts
- To differentiate specific goods from generic ones, contracts must refer to identifiable characteristics, such as make, model, and chassis number for vehicles.
- If a specified item does not exist at the time of contracting, the contract is rendered void.
Vitiating Factors
- A vitiating factor disrupts the consensus necessary for a contract to be enforceable.
- Key vitiating factors include:
- Mistake
- Misrepresentation
- Duress or coercion
- Undue influence
- The presence of any of these factors indicates that the parties may not have truly "met" in agreement, affecting enforceability.
Key Principle on Law Knowledge
- The fundamental presumption is that everyone knows the law; therefore, mistakes regarding legal obligations hold no weight in court.
- Only mistakes of fact can be treated as legally operative for vitiation.
Vitiating Factors
- Vitiating factors are conditions that disrupt or negate consensus in a contract, preventing a true meeting of the minds.
- Four types of vitiating factors:
- Mistake
- Misrepresentation
- Duress or coercion
- Undue influence
Mistake as a Vitiating Factor
- Mistake must be a mistake of fact to be legally operative; ignorance of law is not a valid defense.
- Legal presumption: all individuals are presumed to know the law.
- Mistakes regarding contractual obligations are typically considered mistakes of law, not fact.
Types of Legally Operative Mistakes
- Three classifications of operative mistakes affecting contract validity:
- Common or shared mistake: both parties share a fundamental misunderstanding (e.g., contracting for non-existent items).
- Mutual mistake: both parties have different understandings but the same factual error.
- Unilateral mistake: one party is mistaken without the other party's knowledge.
Importance of Consensus
- The essence of a valid contract is the agreement between parties, aggregating mutual rights and obligations enforceable by law.
- Latin term "consensus ad item" denotes the meeting of minds, crucial for contractual validity.
- In Papua New Guinea dialects:
- "Laka" indicates agreement (though used regionally).
- "Maro" captures the essence of mutual understanding.
Effects of Vitiating Factors
- Presence of vitiating factors, such as mistake, disrupts consensus causing the contract to be invalidated.
- Removal of consensus implies that parties did not freely agree to obligations, undermining enforceability of the contract's terms.
