An investigation has been launched following claims a judge fell asleep in court, causing a child rape trial to be halted.
The Judicial Conduct Investigations Office confirmed it is looking into the allegation against Recorder Philip Cattan, who was presiding over a trial at Manchester Crown Court.
The complaint is that Recorder Cattan nodded off as a young alleged victim was giving evidence this week via video-link in the trial of John Quigley.
The judge stopped the trial following the allegation and it will now be re-listed.
A spokesman for the Judicial Conduct Investigations Office said: " The Judicial Conduct Investigations Office is aware of the allegation that Recorder Philip Cattan fell asleep during a trial at Manchester Crown Court.
"The matter is being considered in accordance with the Judicial Conduct (Judicial and other office holders) Rules 2013."
In a statement, the Crown Prosecution Service said: " The jury has been discharged in the trial of R v John Quigley at Manchester Crown Court following an issue that arose at court during the cross examination of the first complainant in the case.
"The trial will be relisted as soon as possible. The complainants and other witnesses have been kept informed."
Quigley, 49, of Avon Road, Burnage, Manchester, denies a number of sex offences including the rape of a child under 13.
Philip Cattan is a well-known barrister in the Manchester area and is member of the St Johns Buildings chambers in the city.
He has appeared in a number high profile cases and was defence barrister in one of the trials relating to the 2001 Oldham riots.
Mr Cattan sits in Manchester as a recorder, which is a part-time judge.
Judge Gabriel Hutton was disciplined in 2002 after he nodded off during a rape trial at Gloucester Crown Court, causing it to be abandoned.
The Judicial Conduct Investigations Office said Mr Cattan will not be commenting.
