About our case studies

Our case studies look at how specific businesses, products or enforcement actions met the rules. They cover situations such as license applications, product recalls, packaging and labeling disputes, testing failures, tax audits and market entry decisions.

Each case study draws on public records, such as agency orders, court filings and published guidance, or on information shared with permission, and links its sources. We explain what happened, which rules applied and what other businesses can take from it.

Use case studies to check your own processes against real outcomes and to brief your team on risks. Each one ends with practical takeaways you can compare against your own procedures. Get new posts in the Regulator Brief, our weekly newsletter that goes out every Monday.

What you will find

  • Enforcement actions and what triggered them
  • Licensing and market entry examples
