The purpose of the requirement of leave to appeal is to enable the Supreme Court to concentrate on guiding judicial practice through precedent. Therefore, the first alternative ground for the granting of leave to appeal is the most important one. A precedent may relate to the application of law in identical or similar cases or to the consistency of case law. In the first-mentioned case, the precedent provides guidance for resolving similar questions of law in the future. In the latter case, the precedent provides guidance for such practice of lower courts as is inconsistent or contradicts the case law of the Supreme Court. The granting of leave to appeal on the grounds that the case creates a precedent always suggests that the decision of the Supreme Court has general legal relevance.
