An Islamic State terrorist's wife has lost yet another court battle after refusing to stand for a judge because she 'only stands for Allah'.

Moutia Elzahed last year became the the first woman in New South Wales to be found guilty of the offence of disrespecting a judge.

On Friday, the 51-year-old lost an appeal against her criminal convictions and her sentence of 75 hours community service.

Elzahed's lawyer said she remained seated for her religious beliefs because it contradicted she 'only stands for Allah'.

Ms Elzahed claimed the law she was prosecuted under infringed on her right to 'political communication' but that rejected by a Supreme Court Justice on Friday.

'Her Honour's finding that the plaintiff's failure to stand was disrespectful was made in the absence of any evidence that the plaintiff's reason for not standing was religious,' Justice Ian Harrison wrote in his decision. 'Her refusal to stand was not a political communication.'

Magistrate Carolyn Huntsman had previously ruled there was no evidence Elzahed was acting on a genuine religious belief or that true Islamic beliefs compelled such behaviour.

Justice Harrison also found that the prosecution did indeed have valid legal authorisation from the Attorney-General to charge Elzahed in the first place.

Elzahed previously lost a bid to sue the Australian Federal Police (AFP) for a counter-terrorism raid on the house she shared with husband Hamdi Alqudsi.

She made claims police had been violent towards her but the civil action failed and was ordered to pay a $250,000 legal bill, which she has challenged.

Her husband, Hamdi Alqudsi was found guilty in July 2016 of organising for the men to make a border crossing from Turkey and meet up with the ISIS fighters

Her husband Alqudsi was found guilty in July 2016 of organising for helping men to travel to Syria to fight in 2013.

He was slapped with a sentence of up to eight years' imprisonment, with a non-parole period of six years.

Alqudsi was the first to be prosecuted under federal foreign incursion laws.

Elzahed's appeal of her sentence has been adjourned to a later date.
