What is meant by the assertion that the supreme
court is a countermajoritarian institution ?

The assertion that the supreme court is a counter majoritarian institution comes from the question asked by Alexander Bickel in 1962 which tried to address the problem of overpowering of the supreme court over the Senate.

Explanation:

Alexander Bickel believed that the power of just 9 supreme court judges to decide for over 308 million Americans and to change the decisions made in the Senate by a majority of members was not fair as far as a balanced functioning of the democracy was concerned.

the anti federalists was a movement that was opposed to the creation of a us federal government. although they were not as organized as the federalists, they also had a large group of leaders, especially in state politics.

the statement "now, in a large extended country, it is impossible to have a representation, possessing the sentiments, and of integrity, to declare the minds of the people” represents the concerns of the anti federalists.

they strongly believed that the federalists were representing the interests of aristocratic elements of society at the expense of the majority of ordinary people, who lived in a rural society.

their fear for the creation of a strong federal government and the president’s power of veto in their opinion would create a tyrannical rule that would dominate the people. they defended the importance of restraining the government’s power towards people at any cost.
