One of rugby league's most experienced referees has launched an unfair dismissal claim against the NRL after he was allegedly sacked without explanation.

Chris James has officiated 228 first-grade games, including two semi-finals, for the NRL over the course of a decade. The veteran whistleblower oversaw 22 NRL games this year and claims that, as late as mid-July, was told he was in contention to referee the semi-finals. At a subsequent meeting on September 6, referees' boss Tony Archer is said to have commended James' performance and praised his work with younger referees.

However, he was axed just a month later in a move that ended 25 years in the refereeing ranks and prevented his family from being able to see him officiate in one final match.

James is seeking reinstatement or compensation, with the support of the Professional Rugby League Match Officials (PRLMO) and the trade union peak body, Unions NSW. It's understood James lodged his claim with the Fair Work Commission on Monday.
