As I said, you always want to see what the record is. The Ontario legislation, which—full disclosure—I was involved in as a legal adviser, has a six-month limit. I think six months, speaking only for myself, is quite a defensible amount of time. The challenge is that there were some B.C. court cases that struck down their provincial pre-writ spending limits partly under the logic that the limits applied while the legislative assembly was in session.
