An analsys of the d devolution of social security powers to the Scottish Parliament in the Scotland Bill.  Whilst the reforms have been represented as giving Scotland “one of the most powerful devolved parliaments in the world.” it is debatable that this is the case. In any federal system, powers lie by default with the states, not with central government. It is open to the states (and sometimes to local governments) to experiment and to innovate. Scotland will not be able to do this.
