Union Pacific Resources Group, Inc. v. Hankins

Summary

The Supreme Court of Texas held that a proposed class of gas royalty owners did not satisfy the commonality requirement for class certification under Texas Rule of Civil Procedure 42. The proposed class included both proceeds leases and market-value leases, which involve different legal duties and valuation inquiries concerning implied covenants to obtain the best available price. The court reversed the court of appeals and remanded the case for further proceedings.

Holdings

1. A court evaluating class certification must consider applicable substantive law and conduct a rigorous analysis of the actual, rather than presumed, conformance of the claims with Rule 42's certification requirements.
2. The proposed class did not satisfy Rule 42's commonality requirement because none of the identified issues both inhered in the complaints of all class members and were subject to generalized proof.
3. Questions concerning preferential affiliate transactions, third-party sale prices, and marketing fees did not establish commonality for a class combining proceeds and market-value leases.

Questions Presented

1. Whether the certified class satisfied Texas Rule of Civil Procedure 42's commonality requirement when it included both proceeds leases and market-value leases.
2. Whether a court evaluating class certification must consider substantive law bearing on the merits of the claims, including the distinction between proceeds leases and market-value leases.
3. Whether the court of appeals had jurisdiction over the interlocutory class-certification appeal based on an asserted conflict with a prior Supreme Court decision.
