Union flag protester Jamie Bryson (23) has received High Court permission to take part in a parade marking the Battle of the Somme.
A judge also ruled that he can lay a wreath at the Cenotaph in Bangor during the commemoration event on Monday.
But Bryson (right) was warned that he must not make any public speeches or give media interviews.
The Ulster People's Forum campaigner is banned from going within a mile of any public demonstration or procession while on bail charged with offences linked to the dispute.
Bryson, of Rosepark, Donaghadee, Co Down, is accused of encouraging or assisting offences and taking part in an unnotified public procession. He was seeking a temporary lifting of the prohibitions so he could take part in the Somme commemoration event with his band, Bangor Protestant Boys.
Police were said to have no objections, provided he was in civilian clothing and not part of the band.
But Mr Justice Weir decided he could participate and lay a wreath. He stressed that Bryson must not make any public speech or social media comment.
No Press interviews can be given, either, during the temporary relaxation of his bail conditions.
