I find it unprofessional for someone to make such public statements while on the (MNIC) Facebook profile it's mentioned clearly the reason being to invalidate the old card.
Therefore hiding behind the law after doing mistakes could be the lamest of things. I'd expect people who are advisors to the State be more responsible, accept mistakes when they happen & fix them rather than playing dumb (ref: as in "I don't know, I can't say").
On this same occasion I'd like to reiterate that during court proceedings, the same advisor to the MNIC Project mentioned that he is not aware of the Biometric ID Card Project of UK. Yet, he advised our Government on the matter. Well, experts they say.
