The Bolivian supreme court shot down the term limits constitutional amendment from 2009 and he still won the election coz he was well, the most popular candidate.
That didn't fly with the Bolivian opposition who rioted. The US wasn't happy either. The real kicker was the military and police telling Morales to step down, though. Control over the police and military is the key determinant of who wins an attempted coup. He lost that.
The US treats its own constitution with a sort of theoretical reverence, but e.g. the 4th amendment which existed for about 240 years was trashed completely and it barely merited comment. If there were violence (e.g. like the capital riots) because of, say, the 60 year old 22nd amendment being repealed by the supreme court it would be less about the reverence to the constitution and more about flagrant partisanship.
