Final answer:
The incorrect statement is the one claiming CPAs cannot disclose information under a legal subpoena or summons; legal orders can compel such disclosures.
Step-by-step explanation:
The statement that is INCORRECT regarding confidential information is: 4) The rule on confidential client information does not allow a CPA to comply with a validly issued and enforceable subpoena or summons. In fact, CPAs may be required to disclose confidential information if they are presented with such a legal order. This is similar to the precedent set in the case of Branzburg v.
Hayes (1972), where the Supreme Court determined that journalists are not exempt from subpoenas and can be compelled to disclose confidential sources. A concurring opinion in this case suggested that if the disclosure of a source is necessary for a criminal trial, the government has the authority to require it. Accordingly, in professional practice, whether in journalism or accounting, there are circumstances where confidentiality must be breached.
