Final answer:
Important legal precedents from the viewpoint of an IT auditor include the Microsoft antitrust case and the concept of ruling by precedent.
Step-by-step explanation:
From the viewpoint of an IT auditor, there are important legal precedents that can guide their work and decision-making. One such important legal precedent is the Microsoft antitrust case, which involved restrictive practices in the technology industry. This case highlights the gray areas in restrictive practices and provides insights for IT auditors when dealing with similar situations.
Another important legal precedent is the concept of ruling by precedent, where judges look to previously decided cases to guide their decisions. This principle of 'stare decisis' ensures consistency in legal interpretation and can influence IT auditors' understanding of legal issues in the technology field.
