Hi Freeatlast,
If one party is delaying proceedings without good reason, and the court accepts that there is no good reason for the delay, then the court will likely punish the other person with costs. The court has absolute discretion to do this. The court will most likely have already ordered that costs for the adjournment hearings be awarded against the delaying party. Depending on what the document is and how significant it is to the court's final decision, the court may decide to move proceedings along without the document as another form of penalising the delaying party.
