A Tribunal may, if any issue arises in relation to a reference on which in the opinion of the Tribunal, it would be desirable for the Tribunal to have the assistance of an expert, appoint a person having appropriate qualifications to enquire into and report on any matter.

The Secretary must supply the parties with a copy of any written report received under paragraph (1) in advance of the hearing or resumed hearing.

If the Tribunal sees fit, it may direct that the expert shall attend the hearing and give evidence.

The Secretary shall pay such reasonable fees, expenses or allowances as the President may determine to any person appointed under this rule.
