Some common law systems, including Australia, are moving away from the idea of consideration as a requirement. The idea of estoppel or culpa in contrahendo, can be used to create obligations during pre-contractual negotiations. The Classical republican concept of “civil society” dates back to Hobbes and Locke. Once accredited, a lawyer will often work in a law firm, in a chambers as a sole practitioner, in a government post or in a private corporation as an internal counsel.
- Land law forms the basis for most kinds of property law, and is the most complex.
- Although many scholars argue that “the boundaries between public and private law are becoming blurred”, and that this distinction has become mere “folklore” (Bergkamp, Liability and Environment, 1–2).
- When contracts are invalidated for some reason (e.g. a car buyer is so drunk that he lacks legal capacity to contract) the contractual obligation to pay can be invalidated separately from the proprietary title of the car.
However, a thorough and detailed legal system generally requires human elaboration. For instance, the Quran has some law, and it acts as a source of further law through interpretation, Qiyas , Ijma and precedent. This is mainly contained in a body of law and jurisprudence known as Sharia and Fiqh respectively. Another example is the Torah or Old Testament, in the Pentateuch or Five Books of Moses.
There are distinguished methods of legal reasoning and methods of interpreting the Law. The former are legal syllogism, which holds sway in civil law legal systems, analogy, which is present in common law legal systems, especially in the US, and argumentative theories that occur in both systems. The latter are different rules of legal interpretation such as directives of linguistic interpretation, teleological interpretation or systemic interpretation as well as more specific rules, for instance, golden rule or mischief rule. There are also many other arguments and cannons of interpretation which altogether make statutory interpretation possible. Investigating, apprehending, charging, and trying suspected offenders is regulated by the law of criminal procedure.
Roman law was heavily influenced by Greek philosophy, but its detailed rules were developed by professional jurists and were highly sophisticated. In medieval England, royal courts developed a body of precedent which later became the common law. A Europe-wide Law Merchant was formed so that merchants could trade with common standards of practice rather than with the many splintered facets of local laws. The Law Merchant, a precursor to modern commercial law, emphasised the freedom to contract and alienability of property.

Aviation law deals with all regulations and technical standards applicable to the safe operation of aircraft, and is an essential part both of pilots’ training and pilot’s operations. Non adherence to Air Law regulations and standards renders a flight operation illegal. It is framed by national civil aviation acts , themselves mostly aligned with the recommendations or mandatory standards of the International Civil Aviation Organisation or ICAO. Environmental law is increasingly important, especially in light of the Kyoto Protocol and the potential danger of climate change.
