Be clear that I don’t subscribe to that premise, but an ethical relativist would seem to be advocating it merely in holding a relativist position.
An ethical relativist appears to be claiming that ethical principles are dependent upon the determination of moral agents. Thus, such a claim would entail that what an agent believes to be right or wrong is right or wrong for that agent but that agent has no “right” to insist that their determination applies to other moral agents. Ethical determinations are, then, tied directly to the rational determination of the moral agent. Since determinations are will dependent, that is, they must be assented to only after the “will dependent” process of reasoning by the agent. Therefore, ultimately, ethical principles can only be decided by the determination of the will of a moral agent and nothing more.
However, I suspect there is a distinction to be made between what obligates a moral agent and what a moral agent bears responsibility for. Ethical principles may obligate moral agents even when these agents are not fully aware of the obligation. Which essentially means that ethical principles are obligatory, independent of the determination of moral agents.
It is perhaps by confusing or ignoring the difference between obligation and responsibility that moral relativism has some degree of plausibility.
I may be obligated to act in a specific manner because of what I am - a rational moral agent - even when my awareness of my obligation is lacking. So, for example, a drunk behind the wheel of a car is still obligated to drive responsibly even when s/he is unaware of that obligation. Responsibility is another, and separate, consideration.
If the reason an inebriated driver is in the state they are in is because of a sequence of irresponsible choices, then they also bear responsibility for failing to live up to their obligation, whether or not they are aware of it.
However, say, the person was drugged by someone else into their incapacitated state, then while an obligation to drive responsibly remains incumbent upon them, the responsibility for failing to live up to the obligation does not.
