Can I help the parliamentary secretary out to the extent that I can on the advice that I have. The passage which refers to the recovery of petroleum on an appraisal basis apparently refers to a previously existing arrangement where a lease and permit were required to assess, and another lease was required to take oil from a lease to appraise the value of the lease. Those two provisions are being combined into one. That is the advice that I have. I am not sure how far that takes the debate, but perhaps that helps the parliamentary secretary out.
