Why does the man lack a legal basis to challenge the proposed rate increase from the utility company?

The assertion that the man lacks a legal basis to challenge the proposed rate increase can be understood through the lens of proper legal representation. If his attorney is already representing him, it indicates that the attorney is responsible for managing all aspects of the case on behalf of the man. This means that any legal challenge to the utility company's rate increase would typically need to be brought by the attorney. The attorney will have the required expertise and authority to present the challenge in court.

If the man were to attempt to personally challenge the rate increase while being represented, it could create issues such as inconsistent representations or altercations regarding who is entitled to speak for the client. Therefore, while he may still have concerns about the rate increase, his lack of a personal legal standing to act independently in this situation is grounded in the fact that he has already engaged legal counsel to manage his case.

In contrast, the other options suggest reasons that would not necessarily preclude him from challenging the rate increase. For instance, residency in State A typically influences the right to challenge decisions made by local entities, but it does not automatically negate standing if other legal channels are available. The authority of the utility company over case details, as well as the need for sufficient evidence, are important
