Not all nation states have codified constitutions, though all such states have a jus commune, or law of the land, that may consist of a variety of imperative and consensual rules. These may include customary law, conventions, statutory law, judge-made law, or international rules and norms. Constitutional law deals with the fundamental principles by which the government exercises its authority. In some instances, these principles grant specific powers to the government, such as the power to tax and spend for the welfare of the population. Other times, constitutional principles act to place limits on what the government can do, such as prohibiting the arrest of an individual without sufficient cause.

Ex Input:
None of the early appearances of the 'Happy Birthday to You' lyrics included credits or copyright notices. The Summy Company registered a copyright in 1935, crediting authors Preston Ware Orem and Mrs. R. R. Forman. In 1988, Warner / Chappell Music purchased the company owning the copyright for US $25 million, with the value of 'Happy Birthday' estimated at US $5 million. Based on the 1935 copyright registration, Warner claimed that the United States copyright will not expire until 2030, and that unauthorized public performances of the song are illegal unless royalties are paid to Warner. In one specific instance in February 2010, these royalties were said to amount to US $700. By one estimate, the song is the highest-earning single song in history, with estimated earnings since its creation of US $50 million. In the European Union, the copyright for the song expired on January 1, 2017.

Ex Output:

who owns the copyright to the happy birthday song
