I read with interest an article in the recent issue of NIHRC Review (Summer 2008) (“Identity crisis?” by Daniel Holder), which concludes:
There is also a specific human rights impact on British
citizens; namely, when [National Identity Registration] is made
compulsory for renewing British passports, those who conscientiously
object could be left without a passport and, therefore, their right to
enter and leave their own country.
An option for such British citizens born in Northern Ireland is to
obtain an Irish passport (exercising dual citizenship). Of course, that
could raise another conscientious objection to some.
