Similarly, all the residuary subjects not mentioned in the Federal legislative List of the Constitution of 1973 come within the legislative competence of provincial legislatures.
In pursuance of a similar entry related to local self-government in cantonment areas, the federal legislature of the time promulgated the Cantonments Act 1924, whereby it not only established individual cantonment boards to be body corporates but also defined the scope of “local self-governance”, including the political, administrative and financial powers to be conferred on cantonment boards.
As far as the federal legislature is concerned, the governance of cantonment areas falls under the repository of powers/subjects mentioned in the Fourth Schedule of the Constitution of Islamic Republic of Pakistan 1973 ( Federal Legislative List) which includes, but is not limited to, foreign affairs, communication, defence and local self-government in cantonment areas. The relationship between cantonment boards and the federal government is akin to the relationship between local governments and the respective provinces.
