(b) would not be reasonably practicable –

a party, not later than 21 days after notice is given, may object to the tender of the evidence, or of a specified part of the evidence.

(3)  The court, on the application of a party, may determine the objection at or before the hearing.

(4)  If the objection is unreasonable, the court may order that the party objecting is to bear the costs incurred by another party –

(a) in relation to the objection; and

(b) in calling the person who made the representation to give evidence.
