Background

  • Sorenson (surface owner) and Pennaco (mineral lessee) executed a surface damage and use agreement granting Pennaco access for coalbed methane operations in exchange for annual payments and reclamation obligations.
  • Pennaco developed wells, roads, pipelines and water disposal pits, made payments through 2010, then sold/assigned its lease and surface-agreement interests to CEP-M, which assigned to High Plains Gas; neither assignees nor Pennaco thereafter paid or reclaimed the land.
  • Sorenson sued Pennaco and the assignees for unpaid annual payments, reclamation costs, and water-well damages; CEP-M and High Plains defaulted; jury awarded Sorenson $1,055,982.62; district court added costs and attorney fees.
  • Pennaco moved for summary judgment arguing assignment released it from post-assignment obligations (via exculpatory language in the lease or because obligations run with the land); district court denied, treating Pennaco as remaining liable as a matter of law and submitting damages to the jury.
  • District court awarded attorney fees using the lodestar as a base ($124,591.25) and enhanced it by a 2.5 multiplier (to $311,478.13), citing Wyoming statute factors and contingent-fee considerations.

Issues

Issue Plaintiff's Argument Defendant's Argument Held
Whether Pennaco remains liable under the surface damage and use agreement after assignment Sorenson: basic contract rules bind the assignor absent an express exculpatory clause or novation; Pennaco remains liable Pennaco: assignment (and lease exculpatory clause) or covenants running with the land mean post-assignment obligations belong to assignee, not Pennaco Court: Pennaco remains liable; surface agreement is a contract (like lease derivatives); absent exculpatory clause or novation, delegating duties does not relieve delegant
Whether the district court properly treated the summary-judgment denial as a legal determination preserving the liability issue for appeal Sorenson: denial of summary judgment is typically not reviewable, but the order effectively decided liability and thus is preserved as law of the case Pennaco: contended issue was not preserved because it didn’t renew a Rule 50(a) motion on liability at trial Held: The denial operated as a legal ruling fixing liability for trial (issues limited to damages), so the question was preserved for appeal
Whether the surface agreement incorporated the lease’s exculpatory clause Sorenson: the surface agreement did not incorporate the lease; it contains its own terms and binds "operators, agents, employees and assigns" but has no exculpatory release Pennaco: lease contains exculpatory language that should apply to obligations Held: No incorporation — the surface agreement lacked clear incorporation language, so lease exculpatory clause does not free Pennaco under the surface agreement
Whether the district court abused discretion by enhancing lodestar fees by a 2.5 multiplier to account for contingent-fee risk Sorenson: multiplier appropriate because counsel took case on contingency, client could not afford hourly rates, and multiplier is authorized by Wyo. Stat. §1-14-126 factors Pennaco: contingent-fee multipliers are impermissible (relying on Dague) and risk of double-counting makes multipliers improper Held: Enhancement permissible and not an abuse of discretion here — Wyoming statute directs consideration of contingency; court reasonably applied factors and precedent permitting rare multipliers
