Party president Ellen Olfert says the committee will work toward a fair and democratic process for the leadership contest that is to take place in March at the NDP's annual convention.
The committee members include Olfert, Kevin Rebeck (REH'-beck), president of the Manitoba Federation of Labour, three members of the party executive and a former party secretary.
Selinger has faced an open revolt from some senior caucus and party members, but has said he will stay on and has suggested his opponents can run against him.
He has pointed to a little-used section of the NDP's constitution, which says the party leader can be challenged by opponents at any annual convention.
The committee is expected to decide how long a leadership race will last, and may weigh in on whether Selinger should temporarily step down as premier during the contest.
