Residents opposed to FC United's planned new stadium have launched a challenge to the club's planning permission.
The non-league club, formed in protest at the Glazer family's ownership of Manchester United, want to build a 5,000 capacity stadium on the Ronald Johnson playing fields in Moston.
They have been granted planning permission by Manchester council and had hoped to start work later this summer.
However, the Residents United Residents Association, set up in protest at the proposals, are trying to force a judicial review.
They believe that the town hall failed to follow protocol when they gave the club the green light.
Papers were lodged last Thursday, the M.E.N. understands.
Manchester council has 14 days to respond to the challenge, which FC United bosses say they expected.
It will then be down to RURA to decide whether they want to take their appeal to London.
