The National Prosecuting Authority NPA wants the magistrates commission to investigate how Tuletu Tonjeni ended up presiding over the Joe Ferrari Sibanyoni case.
The prosecuting body also wants the commission to probe her use of language which lacked court decorum.
Sibanyoni and his two co-accused, Phillmon Msiza and Mvimbi Masilela, were arrested on May 12 and made their first appearance the next day at the Kwaggafontein magistrates court in Mpumalanga, where they were formally charged with extortion and money laundering.
