Why stare decisis is not applicable in international courts?

Stare decisis, the legal principle of adhering to precedent, is not strictly applicable in international courts because these courts often operate within diverse legal systems and cultures, making uniformity in legal interpretation challenging. Additionally, international law is typically based on treaties, customary practices, and general principles rather than a rigid set of precedents. This flexibility allows international courts to adapt their rulings to the unique circumstances of each case, promoting the evolution of legal norms in a global context. Consequently, while past decisions may be persuasive, they do not bind future rulings in the same way as domestic courts.
