What you described would be a violation of the accountant's fiduciary duty to you as a client.

If an accountant issues an unqualified opinion that the Financial Statements reflect fairly and in all material respects the Assets, Liabilities, Cash Flows and results from operations.... and that turns out to be untrue...And the accountant knew that they were untrue...Then that accountant has committed a fraud.

That is current law. No new laws are needed to establish an accountant's liability on this issue. What's more, every partner in the accounting firm has unlimited liability in such a case. (If you form a partnership, you had better know your partner real well: His liability can be made to be your liability if his actions are found to be within the scope of the partnership.)
