What are the events that must happen in order for the Supreme Court to hear a case over which it does not have original jurisdiction?

The case must be appealed to the court from a lower court, or the court must issue a writ of certiorari telling a lower court to send the case to the Supreme Court for review.

Explanation:

The case must be an appeal from a lower court.

Explanation:

The court system in America works as a hierarchy. Different courts are on different levels, with the Supreme Court being the most powerful. If a case is appealed then it will go to a higher level. It is possible for the Supreme Court to not have original jurisdiction over a case, but eventually, an appeal from a lower court reaches it. The Supreme Court will then give its own ruling, overriding whatever the previous court ruled.
