So, there's this EU case I want to remember called Metock - decided 2008. It basically interpreted Article 3 of the Citizen's Directive 2004/38 as requiring citizens of the EU to have moved from their member state of origin to a host member state before relying on EU law regarding free movement. (Did you understand any of that? Yeah, me neither). 
I was looking at this case, Metock, and I thought to myself - that sounds a lot like Mutton. Hey, I know a Mutton. A Mutton Hawk. MuttonHawk. Muttawk. Metock. It's perfect. 

Thank you Muttawk, your username has saved the day.
