Such a system operated in the former New Hebrides (now Vanuatu) which was administered as a co-dominion by Britain and France until the mid- 1980s. Each country operated parallel police forces, law courts and administrative structures with everyone being able to choose one or the other.
It was cumbersome but worked tolerably well. Unfortunately the requisite imagination and willingness to make such a scheme work in Northern Ireland appears to be lacking in large sections of both communities.
