Final answer:
The Sarbanes-Oxley Act imposes data retention requirements on public companies to prevent the destruction of evidence. Supporters believe it is necessary to avoid corporate scandals and improve transparency, while opponents argue it burdens companies.
Step-by-step explanation:
The Sarbanes-Oxley (SOX) Act, enacted in 2002 after accounting scandals involving major corporations, imposes requirements for data retention on publicly traded companies. SOX mandates that companies retain all business records, including email messages, to prevent the destruction of evidence. Supporters argue that SOX is necessary to avoid corporate scandals and increase transparency, while opponents claim it places an unfair burden on companies. These laws are considered necessary to protect the public by increasing confidence in financial reporting and safeguarding investors from accounting fraud.
