Earlier quoted context omitted.
And who adds or repeals constitutional amendments? The government.
Not sure why you're getting down-voted. Yes, constitutional amendments are repealed by the government. A very challenging majority of government officials, yes, but the government.
In the United States, either Congress or the States may adopt a proposed amendment with a 2/3 vote. However, and importantly, only the States can ratify the amendment with a 3/4 vote. This means that, in the United States, at least, "the government" itself cannot repeal amendments. It requires the approval of at least (at this time) 38 other governments.
