Magistrate Charlie Rozencwajg returned the mixed verdict on Tuesday after overseeing the trial against Thomson, who was accused of misusing union funds while head of the Health Services Union.

Thomson, 49, showed little emotion as he sat in the front row of a packed court room as Mr Rozencwajg handed down his verdicts in Melbourne Magistrates Court.

Mr Rozencwajg found Mr Thomson guilty of charges related to using union funds for sexual services, of making cash withdrawals with his union-issued credit card, of buying cigarettes and firewood for his then wife and for some charges related to paying for travel for his then wife.

Thomson was also found guilty of charges related to using union funds after he left the HSU and had become the federal MP for Dobell.

The former MP  faces a five-year jail term as a maximum penalty.

But some of the charges related to the travel for his then wife were dismissed, as were charges related to buying for in-house movies at hotel rooms.

The verdict followed a trial held before Mr Rozencwajg across December and January, after Thomson first appeared in court more than one year ago.

The allegations against Mr Thomson were first raised almost five years ago.

Thomson was accused of using HSU credit cards and a Flight Centre account to accrue more than $28,000 in personal expenses, including sexual services, adult films in hotel rooms and flights and cigarettes for his then wife between 2002 and 2007, when he was the union's national secretary.

He was also accused of using union funds to pay for personal items after he left the union to become the Labor member for the NSW seat of Dobell in 2007.

He lost the seat in last year's election, standing as an independent.

Mr Rozencwajg went through the various verdicts and the reasons behind them for about 40 minutes.

The court was then adjourned so Thomson could speak with his legal team about the timing of a pre-sentence hearing.
