Maidstone United will be able to compete in the Ryman Premier Division play-offs if they qualify at the end of the season.
A Football Association appeal panel unanimously agreed that the club should be able to take part in the knockout competition for promotion to Conference South.
The Ryman League told the club in February they would not be eligible for the play-offs because of the Football Conference rule against artificial pitches but the FA panel has given the green light for Maidstone to challenge for promotion.
Club co-owner Oliver Ash said: “The Football Association has continued its stance of embracing artificial football turf with its decision today.
“Whatever happens with our promotion push in the next few weeks, this decision is another important one for English football as a whole.”
