International trade is essential for the growth and development of global economies and businesses. As international trade has expanded and developed, so too have the myriad rules and regulations that govern it. The global compliance environment is becoming more complex by the day and can be difficult to navigate without the assistance of experienced counsel. Failure to comply with international trade rules and regulations—even if done so unwittingly—can lead to civil and criminal penalties, monitorships, consent agreements, debarment, reputational damage, substantial administrative burden, legal expense, and unsatisfied business objectives. Increasingly, there also is exposure for individual officers/directors, which can include monetary penalties and, potentially, jail time.

Winston represents a class of professional swimmers alleging World Aquatics (WA) violated antitrust laws by blocking their participation in the competing International Swimming League. After WA won summary judgment, Winston successfully appealed, arguing the court applied improper antitrust standards and wrongly denied certification of a damages class. In September 2024, the Ninth Circuit reversed both rulings, reviving all claims and issuing a landmark ruling on the possible application of the per se rule or quick look review to sports-associations rules. Am Law awarded Winston “Litigator of the Week” Runner-Up recognition for the win. In November 2024, the Ninth Circuit denied rehearing. In April 2025, the district court certified a damages class.

Most states, territories, and local jurisdictions also have tax authorities to ensure compliance with applicable state and local laws and regulations. These tax authorities are generally responsible for collecting taxes, administering tax laws, and enforcing tax compliance in their respective jurisdictions.

A tax controversy is a dispute between a taxpayer and a tax authority such as the United States Internal Revenue Service (IRS) concerning whether the taxpayer has properly reported and paid their tax liability, and otherwise complied with applicable tax law.
