The officials seem to completely disregard the fact that our son currently hold and has always held a British passport, and in order to obtain it we had provided in 1997 documentation that was accepted to confirm our status! It's seems madness that 4 years later we are considered 'in breach of immigration rules' when no one has ever questioned our stay since we started working in 1990!
No-one is suggesting you've ever been in breach of the immigration laws. What happened on 2.10.2000 is that U.K. law changed and clarified that from that date, most EEA nationals had only a conditional right of residence in the United Kingdom rather than an unconditional right.
The expectation at the time was that EEA nationals who wanted the rights of permanent residence should apply for Indefinite Leave to Remain (ILR) like anyone else.
So for the purposes of the British Nationality Act, you were
deemed to be settled prior to that date, but no longer so deemed after that date. Obviously, they didn't retroactively take away the British citizenship of anyone who obtained a benefit prior to then (for example, your son) but they were not under any obligation to continue the deemed settled status for those who had it prior. The option to apply for ILR was available for those who wanted it.
Of course the law changed again in April 2006, and if you meet those requirements you automatically obtain Permanent Residence effective on 30.04.2006 and don't need to apply for ILR. So it appears that the child, while still under 18, is eligible for registration as a British citizen.
