Spurned federal Labor MP Emma Husar is considering launching court action against her party as she fights to hold onto her western Sydney seat.
Ms Husar announced in August she would not contest the next election, as she faced an internal investigation into staff bullying allegations.
However, the member for the NSW seat of Lindsay has since changed her mind and has rejected suggestions she is no longer the Labor candidate for next year's federal poll.
NSW Labor officials will meet on Friday to settle on a preselection process to replace Ms Husar.
But she has told The Australian she will fight the process through the courts if necessary.
Ms Husar has deliberately missed votes in parliament and Labor caucus meetings in recent weeks as she pushes back against the party.
She has also threatened to defect to the crossbench.
Fellow federal Labor MPs are leaving the situation to be sorted out by the NSW branch of the party.
"I think Emma is a good person who's been through a difficult time," Labor MP Jim Chalmers told reporters on Thursday.
Labor MP Patrick Gorman also backed Ms Husar as a "good person", but would not comment on the process.
"Most of us don't get to choose when we leave this place and none of us get to choose when our careers come to an end," he told reporters on Thursday.
