Barry Cowen's fellow Fianna Fail TDs are still waiting to hear the outcome of the investigation.
Fianna Fail's Offaly TD Barry Cowen has been cleared of any wrongdoing in the vote-gate controversy.
The Irish Examiner reports that the decision is due to insufficent evidence and that the cases of the other implicated TDs remain ongoing.
Deputies Timmy Dooley, Niall Collins and Lisa Chambers all apologised for their part in voting irregularities.
Fine Gael TD Noel Rock had made the complaints to the Dail ethics committee.
