Well I think you misunderstood my point, actually I was talking about "genuine resident" who exercised their treaty rights under the Directive in another member state can travel to UK without the family permit using their residence card (Genuine residents usually holds residence card or stamp 4).
The COL means genuine residence and there is no such proof for the judgement ruled the COL is illegal!
when you arrived in to a EU member state with your EU family member, you will be normally given 3 months stamp on your passport and if you wish to stay more than 3 months in the state then you have to apply for the EU1 residence card application but you mentioned
3 months and 1 day so what would it be the immigration status in the state after 3 months you meant that
1 day ? if you don't apply to extend your stay in the state after 3 months then you will be classed illegal, when you travel to UK with this status the UK boarder officers might refuse your entry or you may face more challenges.
treaty rights only start after the three months of moving to another EEA country so obviously
1 day won't be suffice to proof.
As you asked in Ireland you can't just go to GARDA and simply get
free re entry visa without the GNIB garda registration card, in case when traveling to UK without Ireland re entry visa and if they refuse your UK entry then the non EU definitely will be deported to their home country
you can see this in the
second link (No 15) you have produced, that person obtained Ireland re entry visa after he got his stamp 4 (GNIB card).
According to the second link that person IN 2014 had genuine residence in Ireland, on arrival at Manchester he couldn't find anyone to request a 1a code, may be he was lucky but now UK found that peoples using this as a backdoor to UK and now they do check in manchester airport and we can clearly understand that he/her fulfilled the COA (Genuine residence) by having all the sufficient proofs i.e stamp 4 which has given the right to work and live in the state to the non EU.
