An eleven-day stalemate has emerged between residents of Garvaghy Road in Portadown and the local Orange Order regarding a proposed march route through an area with a predominantly nationalist demographic.
The dispute centres on whether the thirty-five Orangemen should proceed along the path authorised by the Parades Commission.
A coalition representing the neighbours has indicated that unresolved tensions here may generate friction for similar events elsewhere in Northern Ireland.
On Wednesday, members of the Garvaghy Road Residents Coalition convened with eleven nationalist community groups to coordinate their position.
Attendees included representatives from the Bogside Residents Association in Londonderry and the Lower Ormeau Concerned Community alongside residents from Crumlin Road and Ardoyne in Belfast.
In a declaration issued earlier this month, these organisations pledged complete backing for the Garvaghy Road inhabitants.
Support for the neighbours has also been voiced through correspondence addressed to Sir Chris, alongside communications from external Protestant community members, Members of Parliament, and Members of Congress in the United States.
The Portadown District Lodge have stated they are ready to pursue additional legal measures to facilitate the march.
The Northern Ireland Office confirmed receipt of a letter supporting the residents and noted that the secretary of state remains engaged with all parties involved.
Musician Paul Weller, Derry Girls star Siobhán McSweeney and The Smiths' Johnny Marr have also signed the correspondence backing the neighbours.
