When the Mayor makes a decision, his 'Record of Decision' sets out the decision that was made, the information that was considered and the alternative options that were considered and rejected when the decision was made. It also sets out whether the call-in process applies to the decision.

The call-in process is one way of holding the Mayor to account.

The purpose of call-in is for the Overview and Scrutiny Board to examine the decisions reached by the Mayor and the reasoning behind those decisions. It enables further public debate to be held on the subject. The Board can then consider whether the decision was appropriate and make recommendations accordingly.
