The relevant legal ruling was made back in May 2011
Here are some details of the judgement
Despite the fact that the ruling actually goes against the EEA Family permit route in your case, personally, I would say that if you are eligible for an Irish passport, then the EEA Family Permit route is very well worth a try.
I say a 'worth a try' simply because it is a low cost option and additionally, it still appears that the Home Office has not yet made any official response to the ruling.
Nothing to lose except for the cost of Irish Passport.
Just don't raise your expectations too high.
Going down the human rights route is of course another possibility, but I fear it may take some considerable time and that you would require the services of a good lawyer. (for good read expensive).
