Full Text of Rule 1042.32
Plain-English Summary
Expert opinions can develop as a case moves forward. This rule lets a party file further or updated expert reports without asking the court first, so long as the court's deadline for producing reports has not yet run and the court has not cut off further reports.
Because a supplemental report may add a new theory of liability or causation, the rule keeps the door open for an evolving case while the court's schedule still sets the outer limit.
Frequently Asked Questions
Do I need the court's permission to file a supplemental expert report?
Not until the court's deadline for producing expert reports has passed or the court has precluded further reports.
Can a supplemental report add a new theory?
Yes. It may introduce new theories of liability or causation.
