THE proposed Fiji Labour Party and its president, Lavenia Padarath, appeared in the High Court in Suva challenging certain parts of the Political Party Decree.
It's lawyer, Anand Singh, said the decree is not aligned with international labour laws and also breaches human rights provisions.
Mr Singh said parts of the decree which infringed international law must be reviewed.
Mr Singh said the Labour group did not challenge the whole decree, lawmaker or the president, who approved the decree, but only a portion of the decree that violated human rights and was also not in accordance with international conventions.
However, representing the government, acting Solicitor General Sharvada Sharma said it would be illegal to challenge the decree.
"This case cannot proceed any further because it is illegal. This case challenges the decree," Mr Sharma said.
He said a portion of the decree amounted to the whole decree and even if they want to remove a full stop or a comma, they were challenging the decree.
"That decree has the force of law," he said.
The court heard the decree came into effect on January 15 this year. For Ms Padarath, the court heard the decree breached her right to privacy as politicians needed to reveal information about their assets and liabilities to the public.
Mr Singh told the court to consider his client's submissions because the court was the only resort they could look to.
The case has been adjourned to Friday for ruling.
