But the final statements let Brinkema, who spent the trial’s early days asking witnesses to break down complex technical topics, push back on each side’s arguments — this time with a solid command of the facts. The court decided that there was a single market comprised of merchants and credit card users, and it required the government to prove harm on both sides — a higher standard to meet.
