English law
Common law is a term with historical origins in the legal system of England. It denotes, in the first place, the judge-made law that developed from the early Middle Ages as described in a work published at the end of the 19th century, "The History of English Law before the Time of Edward I", in which Pollock and Maitland expanded the work of Coke (17th century) and Blackstone (18th century). Specifically, the law developed in England's Court of Common Pleas and other common law courts, which became also the law of the colonies settled initially under the crown of England or, later, of the United Kingdom, in North America and elsewhere; and this law as further developed after those courts in England were reorganised by the Supreme Court of Judicature Acts passed in the 1870s, and developed independently, in the legal systems of the United States and other jurisdictions, after their independence from the United Kingdom, before and after the 1870s. The term is used, in the second place, to denote the law developed by those courts, in the same periods (pre-colonial, colonial and post-colonial), as distinct from within the jurisdiction, or former jurisdiction, of other courts in England: the Court of Chancery, the ecclesiastical courts, and the Admiralty court.
South African labour law
The common law of South Africa, "an amalgam of principles drawn from Roman, Roman-Dutch, English and other jurisdictions, which were accepted and applied by the courts in colonial times and during the period that followed British rule after Union in 1910," plays virtually no role in collective labour law. Initially, in fact, employment law, or "the law of master and servant," was regarded as a branch of the law of lease. As such, the common law did not concern itself directly with collective bargaining; its focus instead was on the rights and duties of individual employees and employers, as reflected in the contract on which their relationship was based. The law did not recognize claims by employees which had not been conferred by agreement. Although the role of the common law is minimal, therefore, it should be noted that the common-law contractual relationship between employer and employee underpins collective labour law in general and collective bargaining in particular.
