Court of Appeal to hear residents' parade challenge over Drumcree dispute A challenge to the decision to allow a controversial Orange Order parade to go down a predominantly nationalist road is due to be heard in court later. The deadlock over the proposed march in Portadown - opposed by residents of the Garvaghy Road - has lasted since last Sunday morning. The stalemate has reopened what was once the most bitter parading dispute in Northern Ireland, with stand-offs in the mid-to-late 90s accompanied by riots, roadblocks and killings. The fresh Court of Appeal application argues that the Parades Commission, the organisation that approved the march, had materially misdirected itself on the police assessment of the potential for disorder. The application also said the commission had not given an accurate representation of PSNI evidence in its decision.
