East African Community Court of Justice Rules of Procedure, 2019. (3) The fee paid to another advocate by the advocate on record shall be shown as disbursement. 16. If there has been a change of advocates the bill of costs of the first advocate may be annexed to that of the current advocate and its total shown as a disbursement and they will be taxed in the ordinary way, the current advocate being heard on it, but the taxing officer may require the first advocate to attend. 17. Where the same advocate is employed for two or more parties and separate proceedings are taken by or on behalf of any two such parties, the taxing officer shall consider in the taxation of such advocate’s bill of costs whether such separate proceedings were necessary and proper, and if he is of the opinion that any part of the costs occasioned thereby has been unnecessarily or improperly incurred, the same shall be disallowed. 18. In taxing the costs as between party and party or for payment of a trust fund of joint executors or trustees who are separately represented, the taxing officer shall, unless otherwise ordered by the Court or a judge allow only one set of costs for such parties, such costs to be apportioned among them at the taxing officer shall deem fit. 19. The taxing officer shall allow the reasonable expenses of a party who appeared in person at the hearing of an application, claim or reference and those of a witness who gave evidence at any such hearing but shall not allow the expenses of any person who may have attended the hearing, unless the Court has so ordered. 95
