The Parades Commission has barred Dervock Young Defenders band from Friday night's Ballymaconnelly Sons of Conquerors parade in Rasharkin.
It's because some band members allegedly misbehaved in Ballycastle on July the 12th.
Sinn Féin MLA Daithi McKay has welcomed the ruling, but it's being condemned by DUP councillor John Finlay as "outrageous".
The Rasharkin parade, which goes through a mainly Catholic-nationalist village, has witnessed sectarian clashes over recent years.
