The company, which manages Tonga's orbital space, is at the centre of a legal case brought by Mr Pohiva over nearly $US50 million it received from China.
Last month, Tonga's Supreme Court ruled the payments were not approved by the government.
According to Matangi Tonga Mr Pohiva told parliament last week that a 2012 Auditor General's report reached the same conclusion but nothing was done.
He suggested the members take turns in twos to do prison time at the weekends and in the mornings so as not to disrupt parliament.
