One of the key arguments in favor of fidelity to law is that it helps to promote the rule of law. When judges and lawyers adhere to the law, they help to ensure that the legal system operates in a fair and predictable manner. This, in turn, helps to promote trust and confidence in the legal system, as individuals and businesses can rely on the law to govern their interactions and resolve disputes.
