In response to your query, the Warrant is legitimate and does not require a wet-ink signature. It is a procedural document issued under Civil Procedure Rule 75, which allows an authority to seek permission to employ Enforcement Agents to recover unpaid Traffic Contravention Debts.
If a bailiff or their company refuses to present the Warrant, it's often because they suspect it may be 'defective'—for instance, due to an incorrect address or another issue. Such a defect could render the enforcement power invalid and potentially lead to a claim for damages against Transport for London (TfL).
Remember, if you find yourself in a situation where money has been taken under a defective Warrant, you have the right to demand evidence of the Warrant and prove its defect. Once this is established, you can rightfully apply for the return of the money and your legal costs.
First, issue a Rule 6 Notice under the Pre-Action Conduct and Protocol, requesting evidence of the Warrant of Control. Be sure to copy in both TfL and the bailiff company. If they respond with excuses, you may proceed to court, claim it's a "complaint," or suggest you file a DSAR. Apply for Relief from Sanctions and request an order compelling TfL to produce the Warrant of Control.
If the Warrant lists your previous address, you are entitled to recover the money the bailiff took and your legal costs. However, before proceeding with a claim, it is wise to allow TFL the opportunity to return the money and explain why the Warrant is defective, providing evidence of your current address. This leaves TFL no option but to act, as their position becomes untenable. TFL may seek to recover their loss from Marston, as their actions exceeded regulatory boundaries by tracing you or using an ANPR camera, which Parliament or the MOJ does not officially authorise.
Then post the Warrant here when you have it.
