According to Radio-Canada sources, Ouellette had already made an initial informal approach about returning to caucus last week, and he was told to wait a few months for the Director of Criminal and Penal Prosecutions (DPCP) to determine whether or not to lay charges against him.

In his letter, however, the member pointed out that there was "every legitimate reason to believe that there will be no development in this file for a long time."
