A dispute over a relatively obscure fishing industry rule is attracting considerable buzz ahead of the upcoming Supreme Court term, as the justices will consider whether to overturn their decades-old precedent providing leeway to federal regulators.

Joining Pro Say this week is Law360’s senior environmental reporter Juan Carlos Rodriguez, who will break down the case and what’s at stake for this administrative law bedrock. Also this week, Walgreens accuses Crowell & Moring of serious ethical breaches in a nine-figure arbitration fight, and lawsuits roll in after the FDA declares that over-the-counter decongestants don’t do too much decongesting.
