“The unwritten law possesses capacity for growth; and has often satisfied new demands for justice by invoking analogies or by expanding a rule or principle. This process has been in the main wisely applied and should not be discontinued. Where the problem is relatively simple, as it is apt to be when private interests only are involved, it generally proves adequate. But with the increasing complexity of society, the public interest tends to become omnipresent; and the problems presented by new demands for justice cease to be simple.” – Justice Brandeis, Supreme Court of the United States, International News Service v. Associated Press, 248 U.S. 215 (1918).
