If police decide that there is enough evidence to lay charges against Ambrose, the Prime Minister's claim of illegal activity would be tested in a criminal court.
Now, the Attorney-General has filed a memorandum in the High Court at Auckland seeking $13,669.45 in costs from Ambrose. Those costs include $3760 for hearing preparation costs and counsel fees; $5076 for general costs including researching and filing; $1377.70 for air travel and $278.52 for taxis.
Counsel for the Attorney-General, Sean Kinsler, said the Attorney-General consented to bringing Ambrose's matter to a hearing just two days after it was filed in the High Court. That caused a "compressed timetable" and only two working days for the Crown to do the necessary pre-hearing work.
He said the total spent by the Attorney-General on the matter, up to the end of the hearing, was $23,442.95.
However, they were seeking what they believed was an appropriate and reasonable rate based on the work done and expenses incurred.
Ambrose yesterday referred questions to his lawyer Ron Mansfield, who was unable to be contacted.
