Private Law and Civil Obligations

Private law governs the legal relationships among individuals or entities—natural persons, companies, associations—by setting out rights, duties and remedies when those relationships break down. Its principal branches are contract law, tort law, property law and unjust enrichment. Contract law enforces freely agreed promises and allocates risks when performance fails. Tort law imposes duties of care and allocates losses for wrongs such as personal injury or property damage. Property law defines rights of ownership, use and security over tangible and intangible assets. Unjust enrichment protects against unfair gains. Together these systems create a comprehensive framework of civil obligations, balancing autonomy, fairness and social order.

A study of customary and statutory inheritance rules in north-west Ethiopia reveals how gaps—such as open-ended time limits for claims and weak mechanisms to align wills with local norms—fuel recurrent familial land disputes. The authors document how women and children in particular lose out when formal laws conflict with community mediation, and they propose reforms to harmonise statutes with customary practices, faster adjudication and legal education to strengthen tenure security.

Another contribution introduces an “open” material-transfer agreement designed for the life-sciences community. This standardised, no-fee licence clarifies rights over biological materials—cell lines, plasmids and other reagents—governing downstream use and redistribution. By lowering administrative barriers and embedding practical conditions for collaboration, the protocol accelerates pre-competitive discovery without compromising commercial follow-on rights.

An authoritative survey of American contract law outlines its dual origins in judge-made “common law” and the Uniform Commercial Code. It clarifies how courts determine when a promise is enforceable—by bargain (consideration) or by reliance—and how contracts are formed, interpreted and discharged. The work highlights modern doctrines that excuse performance for mistake or impracticability, and it reviews the measures of damages and the limited availability of specific performance where money alone is inadequate.

A comparative analysis of the “intermediate field” between contracts and torts examines situations where these two fields overlap or blur. The author shows how pre-contractual duties of care (culpa in contrahendo), protective obligations within contracts and third-party interference with contractual claims create a grey zone. The study argues for a unified theory of civil liability that focuses on the nature of the injured interest rather than on formal categorisation of rules, and it assesses the implications for codified civil law.
