Judicial precedent is the legal principle that courts follow decisions made in earlier similar cases. It helps maintain consistency, predictability, and fairness in contract law. Decisions from higher courts are generally binding on lower courts within the same hierarchy.
Contract law has developed heavily through judicial precedent, with many core principles originating from landmark cases rather than legislation. Courts rely on earlier decisions when dealing with issues such as offer and acceptance, consideration, and interpretation of terms. In Carlill v Carbolic Smoke Ball Co, for example, the court established important principles relating to unilateral offers and intention to create legal relations, which continue to influence modern contract disputes. Judges may distinguish previous cases where the facts are materially different, or higher courts may occasionally depart from precedent to develop the law. In exams, the key issue is understanding how earlier authorities shape legal reasoning and how courts apply precedent to new factual situations.
