The Scottish Constitutional Convention (SCC) was an association of Scottish political parties, churches and other civic groups, that developed a framework for a Scottish devolution. It is credited as having paved the way for the establishment of the Scottish Parliament in 1999.
The Convention has its roots in the Campaign for a Scottish Assembly (CSA), which was formed in the aftermath of the 1979 referendum that failed to establish a devolved Scottish Assembly. Launched in 1980 and led by Jack Brand and later headed by Jim Boyack (father of former Labour MSP Sarah Boyack), the CSA contained individuals committed to some form of Home Rule for Scotland. Most were members of the Labour Party, but many Scottish National Party members took part too.
The CSA kept up the pressure for devolution in the early years of the Conservative government of Margaret Thatcher, which was totally opposed to any form of Home Rule. Eventually the CSA came to the stance that the cause of Scottish devolution would be best served by a convention with more democratic legitimacy invested in it.
The CSA organised the committee, chaired by Professor Sir Robert Grieve, that published the Claim of Right for Scotland. The Claim held that it was the Scottish people's right to choose the form of government that best suited them (a long-established principle, first formally stated in the Declaration of Arbroath, 1320), and which also recommended the establishment of a convention to discuss this.
