As an AI language model, I don’t have real-time data or knowledge of future events beyond October 2021. Therefore, I cannot provide information on the top 10 most important legal rulings around the world in 2023. Legal rulings can vary greatly depending on the region, country, and specific legal context, which further complicates predicting their importance. It’s best to consult legal experts or stay updated with reliable news sources for information on legal rulings as they unfold in the future.
