The ruling means accords calling for the establishment of diplomatic relations and the opening of the Turkish-Armenian border can move to parliament, although there is little sign they will be adopted soon.
The accords, which need parliamentary approval in both countries, have been gathering dust since they were signed by the two governments in October 2009, with Turkey facing a backlash from close ally Azerbaijan, a key energy supplier to the West.
The accords seek to overcome a century of animosity stemming from the World War One mass killing of Armenians by Ottoman Turks, which Armenia -- and some European states and Western historians -- says was genocide, a term rejected by Turkey.
Reading the ruling, court president Gagik Harutiunyan said the protocols “conform with the constitution of Armenia.”
“The decision is final and cannot be challenged,” he said, to shouts of “Shame!” from opposition supporters in the court. Several hundred more protested outside.
Opponents of Armenian President Serzh Sarksyan say the terms of the accords undermine Armenia’s pursuit of further “genocide” recognition and effectively abandon claims to parts of eastern Turkey as an Armenian homeland. Sarksyan says they renounce nothing.
