March 1 Rule. After March 1 of any year and through the conclusion of the annual Selection Meeting, if an inquiring club seeks permission to discuss employment with a person who is under contract for the succeeding season or seasons to another club, to offer him or her a position as a high-level club employee, the employer club is under no obligation to grant such permission if such persons current responsibilities include gathering information on and evaluating draft-eligible players or veteran free agent players. At the discretion of the employer club, however, such permission may be voluntarily granted.
