when term limits have been overturned, the most common method was ________.

When term limits have been overturned, the most common method was a decision by the state Supreme Court. This is based on evidence from multiple sources explaining that term limits, often established by constitutional provisions or statutes, have been overturned most frequently by state Supreme Court rulings. While a bill passed by the state legislature can also be a method, the state Supreme Court decision is the more common method for overturning term limits, as courts sometimes find them unconstitutional or improperly enacted.
