With the Planning etc (Scotland) Act 2006, we tried to introduce a hierarchy, from national developments through to major developments, such as supermarkets, to local developments and the permitted development that the minister has mentioned.We were required to produce a participation statement saying how we would go about drawing up the national planning framework, and we had events all over Scotland at the start of the process, when we produced the consultative draft, which contained various projects.We decided that national developments were, essentially, major infrastructure projects of the scale of the Forth replacement crossing.
