Where it stands
Petition Pending

Awaiting an order on the petition

No decision timeline until the Court agrees to hear the case.

What it’s about
Cherry Rider and other mineral-interest owners allege that the energy companies breached a 2008 settlement concerning Kansas natural-gas interests.
What's at stake
The owners’ effort to seek damages together remains unresolved while the Supreme Court decides whether to hear the companies’ petition.

Summary: written with AI from the case record.

What it's about

Their petition asks whether a damages class may be certified without a practical way to identify its members and when evidence suggests a meaningful number lack the legal right to sue.

In 2008, Oxy USA settled a dispute involving mineral-interest owners in a Kansas natural-gas field; Merit Hugoton acquired Oxy’s local assets in 2014. The owners allege the companies breached the settlement.

The owners first proposed a group limited to people covered by the settlement, then sought approval for a broader group.

Question presented

1. Whether Federal Rule of Civil Procedure 23 permits certification of a damages class even though the district court finds that there is no administratively feasible way to ascertain members of the proposed class. 2. Whether Article III and Rule 23 permit certification of a damages class where the class is defined to include members who lack standing and undisputed evidence tends to show that the number of members who lack standing is not de minimis.

What happens next

The next step is for the Court to decide whether to hear the case. No argument or decision date has been set.
