PETA brought a lawsuit against SeaWorld on behalf of its orca whales.
They claimed that the whales should be released under the 13th amendment which is all about anti-slavery rights.
The case wasn't immediately dismissed and U.S. District Judge Jeffrey Miller actually heard the case. He was the first judge to hear a case about the constitutional rights of animals.
"As 'slavery' and 'involuntary servitude' are uniquely human activities, as those terms have been historically and contemporaneously applied, there is simply no basis to construe the Thirteenth Amendment as applying to non-humans."
PETA responded by saying:
"Today’s decision does not change the fact that the orcas who once lived naturally wild and free are today kept as slaves by SeaWorld.
PETA will regroup and determine how to continue to work for the legal protection they deserve."
We hope that PETA regroups and does something else because it's so sad that these whales are forced to live basically giant bathtubs.
