management and those charged with governance. They need to
implement sufficient internal controls that helps management in
detecting frauds .

- to obtain reasonable
assurance that the financial statements are free from
material misstatements. (material misstatements can be
international misstatements that are called as frauds or they can
be unintentional misstatements that are called as errors.)
- For obtaining such reasonable assurance, the auditor is
liable to maintain
professional skepticism ( that is he needs to have an
attitude of questioning and being alert to the situations that
indicates risk of misstatements).
- If auditor identifies risks of fraud or error , then he is
responsible to respond
appropriately to such risks i.e. he needs to develop an
audit plan to assess further.

auditor can't be held liable for not detecting frauds because audit
has certain limitations such as timing, management involved into
fraud and others. Auditor is responsible to obtain
assurance and not to detect frauds.
