Form of case
19. The case shall consist of paragraphs numbered consecutively and shall state, as concisely as possible, the circumstances out of which the appeal arises, the contentions to be urged by the party lodging the case and the reasons of appeal. Reference by page and line to the relevant portions of the record as printed shall, as far as practicable, be printed in the margin, and care should be taken to avoid, as far as possible, the reprinting in the case of long extracts from the record. The taxing officer, in taxing the costs of the appeal, shall, either of his own motion or at the instance of any party, inquire into any unnecessary prolixity in the case and shall disallow the costs occasioned thereby.
