Fiji's Opposition will return to Parliament when the House resumes next week.
Members of the (NFP) National Federation Party and SODELPA walked out of Parliament last month after three of their petitions were dismissed by the Speaker.
NFP leader Biman Prasad said while they had resumed parliamentary committee duties, the issue of the petitions remained.
The Opposition was yet to receive a response from the Speaker.
Mr Prasad said the petitions called for a review by the Standing Committee on Natural Resources of a proposed mining project in Sigatoka.
But Speaker Ratu Epeli Nailatikau said the petitions did not have handwritten signatures attached and online signatures would not be considered.
Meanwhile, formerly suspended Opposition MP Pio Tikoduadua has now returned to work.
Mr Tikoduadua was suspended in September for six months after refusing to apologise for verbally abusing the prime minister in Parliament.
