Why does it make sense that a supreme court decision is not permanently binding?

It makes sense that a Supreme Court decision is not permanently binding because the Court's interpretations of the law can evolve over time as societal values and norms change. Allowing for the possibility of revisiting and potentially overturning past decisions ensures that the law remains responsive to the needs of society and reflects current understanding and perspectives. Additionally, the principle of stare decisis, which guides the Court to respect precedent, is balanced with the recognition that legal interpretations may need to adapt to new circumstances.
