There's still plenty of time for that.
Trying to recoup anything at all from Halligen would merely be throwing good money after bad and they have more to worry them than tilting at this particular windmill.
Just another opportunity to get the boot into the parents of a missing child; but one which has even less credibility than most of the others.

The McCanns' spokesman, Clarence Mitchell, said: "Oakley International was contracted to help with the search for Madeleine.
Due diligence was carried out at every stage and payment was only made for work properly carried out. It was only towards the end of the six-month contract that question marks were raised about delivery in some areas and the contract was terminated."
The McCanns did not contact the police about Halligen, who visited their home, but his behaviour aroused suspicions at an early stage among the couple and their advisers.
Oakley International secured the contract from the Find Madeleine Fund to monitor the phone hotline, sift through CCTV footage of possible sightings and carry out investigative work.
However, it was terminated after the British double-glazing millionaire Brian Kennedy, who has underwritten the fund's work, raised concerns. Documents reportedly show that Halligen's company was withdrawing large amounts of money for personal use.
