A collective title is an expression by which two or more pieces of legislation may, under the law of the United Kingdom, be cited together. A famous example is the Parliament Acts 1911 and 1949.
The United Kingdom, officially the United Kingdom of Great Britain and Northern Ireland but more commonly known as the UK or Britain, is a sovereign country lying off the north-western coast of the European mainland. The United Kingdom includes the island of Great Britain, the north-eastern part of the island of Ireland and many smaller islands. Northern Ireland is the only part of the United Kingdom that shares a land border with another sovereign state—the Republic of Ireland. Apart from this land border, the United Kingdom is surrounded by the Atlantic Ocean, with the North Sea to the east, the English Channel to the south and the Celtic Sea to the south-west, giving it the 12th-longest coastline in the world. The Irish Sea lies between Great Britain and Ireland. With an area of 242,500 square kilometres (93,600 sq mi), the United Kingdom is the 78th-largest sovereign state in the world. It is also the 22nd-most populous country, with an estimated 66.0 million inhabitants in 2017.
Legal citation is the practice of crediting and referring to authoritative documents and sources. The most common sources of authority cited are court decisions (cases), statutes, regulations, government documents, treaties, and scholarly writing.
The Parliament Acts 1911 and 1949 are two Acts of the Parliament of the United Kingdom, which form part of the constitution of the United Kingdom. Section 2(2) of the Parliament Act 1949 provides that the two Acts are to be construed as one.
