Malawi's constitutional court has stopped impeachment proceedings against President Bingu wa Mutharika, pending a review of the parliamentary guidelines on how to remove him.

The court's ruling Wednesday comes after a private lawyer challenged the legality of the impeachment motion against the president. He said Mr. Mutharika is arguing that the procedures, which were to begin Thursday, are unconstitutional and are not in accordance with the rules of natural justice.

Malawi's parliament last week introduced the impeachment motion against Mr. Mutharika, charging him with misuse of public funds in setting up his own party.

Mr. Mutharika - a former economist - has won praise from donor nations and aid agencies for his efforts to adopt economic reforms and stamp out corruption.
