What must GPSC rulings be consistent with?

The correct answer is that GPSC rulings must be consistent with current legal standards. The Georgia Public Service Commission (GPSC) operates within a framework of laws and regulations that establish how it can operate and what it can regulate. It is essential for the commission's rulings to adhere to these legal standards to ensure that they are enforceable and valid. This alignment with current legal standards upholds the rule of law, safeguards the rights of those affected by the Commission's rulings, and ensures that the decisions made are in accordance with the established statutory and regulatory frameworks that govern public service utilities.

In contrast, public interest standards, environmental regulations, and state constitutional requirements, while important aspects of governance, do not specifically dictate the foundation upon which GPSC rulings are made. The primary obligation of the GPSC is to ensure that its decisions conform to the prevailing legal standards, as this provides the necessary authority and legitimacy for their determinations.
