The Attorney General in the Somare administration claiming to be Papua New Guinea's government says the timing of the suspension of the Chief Justice by the rival O'Neill government is questionable.
Peter O'Neill says his cabinet has suspended Sir Salamo Injia to allow for allegations of misconduct in office against him to be heard.
This comes as the Supreme Court is due to rule again on the validity of the O'Neill government.
In December, the court ruled that Mr O'Neill's election as Prime Minister was unconstitutional.
Sir Arnold Amet revealed the O'Neill regime's intention to suspend Sir Salamo late last year.
"Procedurally, they are entitled to and can do this. I think the concerns have been previously and now as well is the timing and the fact that the Chief Justice is presiding over matter related to the previous decisions of parliament and subsequent judgement of the court itself."
