The Heritage Protection Bill for England failed to be included in the Government's Draft Legislative Programme for 2009/10 announced in June 2009. This indicates that it is very unlikely to be included in the legislative business of the next Parliamentary session. The Council for British Archaeology are understandably disappointed, though English Heritage has indicated that many of the reforms can go ahead without it.
This legislation would have unified the two separate systems that currently exist and made the process of protecting heritage much simpler and more effective.
Apparently it's been pushed off the agenda by financial reforms.
