Where defendants ignored a so-ordered stipulation which was a conditional order of preclusion, they are precluded from adducing evidence at trial. The order became self-executing when defendants took no action within the 30-day time limit in which they were to provide the requested discovery or "request [an] immediate conference" to explain why they could not do so. Defendants did neither.
