Practice Highlights

Representative Matters

  • Successfully defended a European pipe manufacturer in a complex multi-party products liability lawsuit brought by a leading E&P company for damages sustained in a downhole casing failure. Before experts were designated, metallurgically proved that the pipe in question was not – and could not have been – manufactured by the client. As a result, the client was dismissed from the suit.
  • Defended a coupling manufacturer in a complex multi-party products liability lawsuit brought by an E&P company for damages sustained in a downhole casing failure. Successfully resolved the case when the credible evidence indicated that the couplings were manufactured to design specifications, without a manufacturing defect – and that the operators use of P110 in a H2S rich environment was problematic.
  • Defended a construction contractor to favorable resolution against condominium owners’ association’s claims for multi-million dollars in damages alleging DTPA violations, fraud, misrepresentation, breach of contract, violations of Texas statutes and attempts to obtain personal liability of a corporate officer.
  • Successfully prosecuted and tried a client’s construction defect claims against contractor obtaining a favorable verdict, damages and attorneys’ fees.
  • Successfully defended a prominent timber company in a partition suit, and prevailed, among other claims, against the partition of the acreage in kind.
  • Defended a condominium owner’s association in a complex Trespass to Try Title and Partition suit. This resulted in a resolution where the plaintiff paid the defendant condominium owners a significant settlement amount and entered into various agreements related to the future relationship of the parties as it pertained to the partition, re-platting, drainage and use of utilities.
  • Obtained successful summary judgment, disposing of all claims in the defense of a Houston oil refinery against claims brought by its contractor’s employees for injuries sustained from an explosion and resulting fire that occurred during the construction of a renovation project. 
  • Represented various construction contractors in wrongful death claims, alleging a myriad of claims, including insufficient training, improper equipment, no safety culture and poor supervision/management through diligent discovery, extensive client preparation and obtaining favorable witness and expert testimony. This resulted in our ability to posture each of those lawsuits for a favorable resolution based on the state of the credible evidence on the issues of liability and/or damages.
