The move follows a complaint by Ucatt member Terry Renshaw after he saw a video on YouTube of Dooley addressing a rally of electricians during their recent protests against the BESNA pay deal.
Renshaw complained that Dooley swore while talking to the crowd with a megaphone.
Renshaw is one of the original “Shrewsbury 24” pickets convicted over strike action in the building industry in 1972.
He is leading calls for a judicial review of the convictions and claimed Dooley’s actions have harmed his case because the bad language took place in front of a Shrewsbury pickets banner.
The highest profile member of the Shrewsbury 24 is actor Ricky Tomlinson who’s catchphrase is “My Arse”.
Renshaw’s complaint states: “In the video he (Dooley) is standing in front of a banner which has the Shrewsbury pickets on it, including my face.”
He claims Dooley’s action could “jeopardise” the pickets chances of getting a Court of Appeal hearing after 40 years.
Dooley appeared at a disciplinary hearing last month but had to leave early because of work commitments.
The Executive Council heard the charges in his absence and withdrew his union membership.
