A judge in Belfast will rule Thursday on the latest legal attempt to block a no-deal Brexit.
Raymond McCord, whose son was killed in the political violence that dogged Northern Ireland for decades, is trying to get the court in Belfast to declare that leaving the European Union without a deal would breach the peace deal known as the Good Friday Agreement. EU membership allowed for an open border on the island of Ireland -- a key element of the peace accord -- and a no-deal exit could put that at risk.
