Maguire remained a TD until 1927. He had initially indicated a willingness to contest the June 1927 general election as a Sinn Féin candidate but withdrew after the IRA threatened to court-martial any member under IRA General Army Order 28, which forbade its members from standing in elections. (Despite this ban, IRA officers Seán Farrell (Leitrim–Sligo) and John Madden (Mayo North) contested the election, the latter successfully).
