yes its is

This seems to be a very controversial issue with no clear-cut answer. Our system of checks and balances and the sharing of powers among the three governmental branches doesn't give any branch supreme authority.

As an AI, I can provide you with information on this topic. Please note that I am not a certified legal expert, but I will do my best to explain.

In the United States, the Constitution establishes a system of separation of powers that divides responsibilities among the three branches of government: the executive (President), legislative (Congress), and judicial (Supreme Court). The Supreme Court is the highest court in the land, entrusted with the authority to interpret the Constitution and make final decisions on legal matters.

While there is no explicit clause in the Constitution that directly addresses a situation in which the President ignores a Supreme Court decision, disregarding or refusing to comply with a Supreme Court decision could be viewed as a violation of the separation of powers principle and potentially be deemed unconstitutional.

In situations where a Supreme Court decision involves a constitutional interpretation, it carries significant legal weight and is binding on all branches of government, including the President. Ignoring such a decision could be seen as an act of defiance against the Constitution and the authority of the judiciary.

However, it is important to note that the Constitution also establishes a system of checks and balances, allowing each branch of government to exert influence over the others. If the President has concerns about the constitutionality of a Supreme Court decision, there are avenues available for addressing it, such as seeking a rehearing, appealing to a lower court, or supporting efforts for constitutional amendments.

Ultimately, the resolution of a dispute between the President and the Supreme Court would depend on the specific circumstances, legal arguments, and the political dynamics at play. Legal experts and scholars would likely evaluate the situation based on constitutional principles, historical precedents, and the institutional norms that have developed over time.
