This casebook focuses not only on the rules and principles of contract law, but also on the lawyer’s role in planning and drafting contracts and on the richness of contract theory. The book opens with materials tracing a contracts dispute from the agreement stage through contract breakdown and litigation. It includes comprehensive coverage of contract law theories of obligation, including bargain, promissory estoppel, unjust enrichment, and tort arising in the contract setting. The publication is primarily a casebook designed to help students develop important analytical and critical skills, but it also includes some notes and problems addressing the nature, function, and limits of contract and related law. The sixth edition includes new cases and secondary sources that present recent and developing issues of contract law, including the influence of technology, and updates and enriches existing material.
