What the split means

The ruling rejected President Trump’s effort to restrict automatic citizenship for most people born in the United States. One detail that got attention is that Kavanaugh reportedly agreed the order could not take effect, but on a different legal theory than the majority used.

TL;DR: 6 justices said keep birthright citizenship; 3 dissented.
