Background: I had received a Family Permit previously but it had expired 9 months ago. I'd started the process of applying for a Residence Card but when I asked for my passports back the whole package was returned with a letter stating I didn't have enough evidence, so no CoA.
I travelled to Canada alone and returned after two weeks.
I had my passport, a copy of my husband's German passport, our marriage certificate, and two bank statements (his and mine) for proof of address.
I stated clearly that I was seeking to enter as an EEA spouse.
(This is important because they could give you a tourist stamp otherwise.)
The border officer was initially a little hostile, questioning why I had remained in the country when my Family Permit expired so long ago. He seemed to think that I had over-stayed. I explained to him that I was entitled to be in the country as long as my husband was exercising treaty rights.
He then took all my documents and handed me a piece of paper that stated that the documents were being held. He asked for my husband's phone number so I gave it to him. He said he needed to check with his superior and left his booth. After about 10 minutes he returned and stamped my passport with a 6 month leave to enter. He seemed almost apologetic for his confusion earlier.
My husband was never called.
I think if more people exercised their freedoms they would be much harder to take away. I myself regret having gone through the family permit process the first time around (and providing way too many unnecessary documents) when I really didn't need to, I encourage others that are applying for FP to question their applications as well.
p.s. Thank you Jambo for your replies to my questions in previous posts
