@Enceladus, Would re-sealing give rise to a new date for the warrant of control?
OP, pl don't let this stop you paying.
My understanding is that no it wouldn't. The Enforcement Authority applies to the TEC for a warrant which is called a Local Authority Warrant of Control. In most cases the TEC seems to process these the same day. And (virtually) seals the warrant request and informs the EA. The warrant is valid for a year.
If it transpires that the warrant is unenforceable at the address stated, then the EA can apply to have the existing warrant re-sealed with a new address. Hence the terms seal and re-seal. The clock remains running from the original date.
Since the original warrant expires after a year the EA would need to re-apply to the TEC for a new warrant to continue to enforce.
In theory, in order to have a warrant re-sealed the EA is supposed to adduce evidence, to the TEC, to confirm that the new address is correct and relates to the person or entity named on the warrant. Hence they can't just look at the phone book (if there still is one).
