Montana Supreme Court

Parenting of C.R.J.

July 14, 20262026 MT 151

Summary

The Court affirmed a discovery sanction limiting the mother's counselor's testimony about treatment and records created after the parenting evaluator's report. It held that the mother's deliberate failure to produce current mental-health records, despite discovery obligations and a court-approved stipulation, caused substantial prejudice and justified the tailored exclusion. No separate opinions were filed.
