Papua New Guinea's opposition has called again for parliament to be recalled to address the coronavirus pandemic.
Its leader says the government's declaration of a state of emergency lacks legal standing.
Belden Namah said the government must be recalled immediately to pass emergency legislation in accordance with the constitution.
The James Marape-led government declared a state of emergency which came into effect on Tuesday.
Emergency measures include a ban on travel from district to district, and province to province.
Also, all schools and non-essential businesses are to shut for 14 days.
But Mr Namah said such an SOE must be approved by parliament passing an Emergency Act to provide a legal basis for the measures.
He accused the government of being unprepared to respond to a health crisis it had months to plan for.
Parliament adjourned at the end of February, to resume on 12 May.
