How Judge Stark decides

Patterns drawn from this judge's own signed orders. Every observation links to the order it came from.

What persuades

In Cirba, Stark excluded an expert who offered no reliable method for translating customer survey data into the claimed apportionment figure, while allowing opinions supported by an adequate foundation.

“Mr. Mayfield has not done so here.”

In Noble, Stark required an intervening change in law, new evidence, or a clear error rather than a repeated disagreement with the prior ruling.

“Plaintiff has failed to demonstrate any of the aforementioned grounds to warrant reconsideration”

Procedural preferences

In Align, Stark applied the local rule narrowly, granting only limited clarification while denying the balance of the reargument request.

“motions ‘should only be granted sparingly.’”
