The Minister of Climate Change, Bruno Leingkon, is facing charges of breaching aviation regulations.
He is alleged to have been drunk on a trip last year.
It's claimed he harassed a female pilot, causing her to return the flight to Santo soon after taking off.
Friday, after his appearance in a preliminary inquiry, Leingkon's associates told journalists they could not take his photo.
When it was pointed out this was not the case, the cabinet minister escaped by using a back door in the courthouse.
