I'll take a stab at that just to explain first of all the requirements for memoranda to cabinet.
The Privy Council Office puts out a guide for memoranda to cabinet for departments and ministers. We ask departments to include where appropriate: adverse consequences of proceeding and not proceeding; legal risk assessments including charter and trade; horizontal policy impacts across the government's agenda; privacy impacts; official languages considerations; provincial-territorial-regional considerations and strategies, including federal spending power considerations; gender issues; private and voluntary sector implications; the different groups that are consulted and their views; sustainable development aspects; as well as international perspectives and comparative analyses.
