Final answer:
Intervention in legal proceedings in California is allowed in certain circumstances, such as when a governor requests a federal court hearing, in criminal matters, or when state courts are unable to reach a decision. Examples include Proposition 187 and cases of inter-state disputes.
Step-by-step explanation:
California allows intervention in legal proceedings under certain circumstances:
- If a governor requests a federal court hearing.
- If it involves a criminal matter.
- If the state courts are unable to come up with a decision.
For example, in the case of Proposition 187, a controversial ballot initiative that aimed to make it illegal for any undocumented alien to receive public benefits, a federal court determined that the measure was preempted by federal immigration laws.
Intervention can also occur when there is a vacancy on the Supreme Court and a new justice must be nominated, or when one state sues another, such as Arizona suing California over water rights.
