Answers
1. D – Judicial decisions
Explanation: Under Article 38 of the ICJ Statute, judicial decisions are only subsidiary means for determining international law. They assist in identifying rules but do not themselves create binding law.

Explanation: Obligations erga omnes are owed to the international community as a whole, such as prohibitions on genocide or slavery, recognised in Barcelona Traction.
