Treaty of Lisbon (No. 7)

I appreciate that my hon. Friend said that the mechanisms must be examined, especially in consultation with Select Committees. However, has he decided whether he wants the scrutiny to be similar to that of Select Committees, which scrutinise the Executive's actions and may reach a different policy view from Government, or whether he wants the Committees to police subsidiarity and proportionality? Those are distinct functions, and I wonder whether my hon. Friend has already formed a view.
