Appeal procedure to Supreme Court follows civil procedure rules, with discretionary costs and mandated effect when High Court rulings are altered. Section 35M directs that appeals under the designated provision shall, so far as may be, follow the Code of Civil Procedure rules applicable to Supreme Court appeals from High Court decrees, without affecting Section 35K(1) or Section 35N. Costs of the appeal are at the Supreme Court's discretion, and where the High Court's judgment is varied or reversed, effect must be given to the Supreme Court's order in the manner provided in Section 35K for altered High Court judgments.
