In its decision, the tribunal said that in making the allegations, Mr Orlov had expressed himself in an unrestrained, unprofessional and at times outrageous manner.
In doing so he had "utterly failed in his duty to the legal profession, to the court, and to the public in terms of their reasonable expectations of his behaviour".
Law Society president Chris Moore said as officers of the court, lawyers were expected to treat others involved in the court processes with respect.
"The allegations made by Mr Orlov undermined processes of the court and the dignity of the judiciary and breached his over-riding duty as an officer of the court."
The tribunal found the charges proven on October 18 following a five-day hearing. It has now ordered that Mr Orlov be struck off but has reserved its reasons.
Mr Orlov previously represented former Zion Wildlife Garden operator Patricia Busch during a long-running feud between her and her son, 'Lion Man' Craig Busch.
