The power to make regulations for a union territory, and the Article rewritten after the merger

Background

The Constitution gives the President power to make regulations for some union territories, and that power sits in Article 240. The Article named Dadra and Nagar Haveli and Daman and Diu as two separate union territories. When the two were merged into one, the Article could no longer stand as it was written. The merger law therefore amended the Article to put the single merged union territory in place of the two older names. The power itself stayed, and what changed was the name of the union territory written into it. This is the pattern whenever a union territory is reorganised: the Article and the Schedule that name it have to be amended too. A regulation under this power is made for a union territory and not for a state. The Article is read with the First Schedule, because both had to be changed by the same merger law.
