Unionist residents in east Belfast are attempting to intervene in a High Court challenge to flag protests in the city, it has emerged.
Lawyers for a number of people in the area want permission to be included as a notice party in proceedings brought by a nationalist man living close to the scene of demonstrations.
The development came as a hearing date for the case against the PSNI and the Secretary of State was put back to June.
A nationalist resident granted anonymity claims unauthorised parades are being allowed from east Belfast to the city centre.
According to the case being made out, legislation which requires the Parades Commission to be notified about processions has been repeatedly violated.
It emerged yesterday that some east Belfast unionists are seeking to be represented in the challenge.
A judge will decide next month whether to grant the unionist residents notice party status.
