Article 48 Summoning of witnesses
In any proceedings under these Rules the court may allow or direct any person to take out a witness summons in Form B requiring the person named in it to attend before the court and give oral evidence or produce any document.
An application by a person allowed to take out a witness summons shall be made by filing a statement giving—
the name and address of the person making the application and of his solicitor, if any;
the name, address and occupation of the proposed witness;
particulars of any document which the proposed witness is to be required to produce; and
the grounds on which the application is made.
A witness summons shall be served on the witness personally a reasonable time before the day fixed for his attendance and he shall be entitled to the same conduct money and payment of expenses and loss of time as if he had been summoned to attend the trial of an action in the High Court.
