Self-enforcing (edit: actually self-executing is the proper legal term) here means that the constitutional amendment doesn’t require a separate act of Congress. The opinion addresses this and says if the 14th Amendment wasn’t self enforcing (edit: executing), some absurd results would ensue. One would be slavery would still be legal.
