Thank you. There is no authority to revoke a writ once it has been issued. In the spring of 2020, we were actually in a situation where we had municipal elections that were about to commence, which don't use a writ, but we also had orders already issued, directing me to issue writs for provincial by-elections that would be held in June 2020. The only option available was for the legislative assembly to direct that I not issue a notice of election for the municipal elections and order me not to issue the writs of election as directed by the Lieutenant Governor in Council.
The only option available in New Brunswick is legislative intervention. There is no authority under the elections act to revoke a writ once it has been issued, or even to not issue the writ once the order directing me to issue the writ has been given.
