A lawyer's comparison of a judge to a monkey is the subject of one of scores of complaints made about legal aid attorneys over the past four years.
Most are dismissed - and many are vexatious, the Ministry of Justice says.
Complaints probed by the Ministry of Justice's independent investigators are to do with lawyers not preparing properly for cases, not following clients' instructions or sending incorrect invoices.
A list of 161 complaints made last year have been released by the ministry, including the case of a lawyer who "sent an email with a remark about a judge and included a picture of a monkey".
A Legal Complaints Review Office summary of the matter reveals more about the banana skin that tripped the unnamed lawyer.
