Hello my name is ***** ***** I will help you with this.
Could you please explain your situation a little more?
Yes they do. As the Channel Islands are within the EU for the purposes of the single market etc as have obligations under the various Treaties, then anywhere in the EU can issue a summons.
So yes, it would be valid.
Can I clarify anything for you about this today please?
It may take me some time to look at this.
I am still looking but not yet.
