The common law and ISA 250

​The Application of Common Law in Auditing under ISA 250

International Standards on Auditing (ISA) 250, “Consideration of Laws and Regulations in an Audit of Financial Statements,” mandates auditors to acknowledge the legal framework within which the auditing process operates. This standard highlights the necessity for auditors to consider laws and regulations that significantly affect the financial statements of an entity. Common law, as a fundamental aspect of many legal systems, plays a critical role in this context, especially in jurisdictions where it forms the basis of judicial decisions and statutory interpretations.

ISA 250 requires auditors to consider laws and regulations when conducting audits. Common law affects this process in several ways:

1. Duty of Care: Under common law, auditors owe a duty of care to their clients and potentially to third parties, depending on the jurisdiction. This concept demands that auditors perform their duties with due diligence to avoid negligence. Case law, evolving from common law principles, often defines the scope and specifics of such duties, influencing how auditors approach their professional responsibilities.

2. Fraud and Illegal Acts: Auditors must consider the implications of fraud and illegal acts on the financial statements. Common law helps define what constitutes fraud and the legal repercussions of such acts. The precedents set in common law jurisdictions serve as a guide for auditors to identify and address potential fraud during an audit.

3. Contractual Obligations and Delict: Auditors often engage with clients through contracts, and common law governs these agreements. The interpretation of contractual clauses, remedies for breach, and liabilities in tort are typically determined by common law, guiding auditors in managing their legal risks.

4. Professional Negligence: Common law cases frequently address issues of professional negligence. These cases provide benchmarks for what is considered acceptable professional behavior, thereby influencing auditing standards and practices prescribed under ISA 250.

The application of common law in the context of ISA 250 has several implications for auditors:

• Legal Compliance: Auditors must ensure that the financial statements they audit comply with the laws and regulations applicable in a particular jurisdiction. Common law influences these regulations and their interpretation, thereby affecting the audit process.

• Assessment of Legal Risks: Understanding the nuances of common law allows auditors to better assess the legal risks associated with non-compliance of laws and regulations by the auditee. This risk assessment is crucial in planning and executing an effective audit.

• Litigation Risk: Auditors need to be aware of the litigation risks involved in their profession, particularly those related to negligence or breach of duty. Common law, through its rich repository of case law, provides a framework for understanding potential legal challenges and preparing for them.

Common law plays an integral role in the application of ISA 250, as it shapes the legal environment in which audits are conducted. By influencing the definition and treatment of legal concepts such as duty of care, fraud, contractual obligations, and professional negligence, common law directly impacts the responsibilities and practices of auditors. It is essential for auditors operating in common law jurisdictions to have a profound understanding of these legal principles to ensure compliance with ISA 250 and to effectively manage their professional risks. As laws evolve, so too will the common law interpretations that underpin these changes, continuously affecting the auditing profession. Understanding and adapting to these changes is crucial for auditors to uphold the integrity of the financial reporting process.
