Independent candidate Arnold Cassola has written to the Commission for Administration of Justice to investigate Melvin Theuma's allegation that Keith Schembri approached Judge Tonio Mizzi to arrange for bail for the accused of Daphne Caruana Galizia's assassination.

In his letter to President George Vella, as chairperson of the commission, Cassola referred to media reports of the testimony given by Melvin Theuma, a middleman in the Daphne Caruana Galizia murder who was given immunity to divulge details of the plot.

The reports said that "Yorgen Fenech (the man accused with complicity in the murder) claimed that (Keith) Schembri, at the prime minister’s (Joseph Muscat) behest, had approached former judge Antonio Mizzi to arrange for bail to be given to the three accused".

If this this true, Cassola said, this goes against the code of ethics for members of the judiciary which state:

“13. Members of the Judiciary shall not discuss out of Court, cases that are pending in court. In full respect of freedom of expression members of the Judiciary should discourage persons from discussing, in their presence cases that are sub judice.  

20. Members of the Judiciary are obliged to pronounce in open Court all communications made to them and to inform the President of Malta of such communication as provided for in the Code of Organization and Civil Procedure.

Cassola requested an investigation into the allegation.
