Reputed Law Firm Handling Appeals Nationwide

Pierce & O’Neill, LLP has earned a strong reputation for arguing and preparing cases at the appellate level. Our appellate practice encompasses many different areas of law, including oil and gas matters, land use disputes and high-stakes commercial litigation. Due to our considerable success and experience in the appellate field, other lawyers regularly seek out our firm when preparing and evaluating their own appellate case strategies.

Over Four Decades Of Focused Practice

With careers that span more than four decades, Jesse Pierce and Jack O’Neill have successfully argued dozens of appeals in state and federal courts across Texas and nationally. Our firm’s founders are complemented by numerous skilled attorneys, many of whom draw on relevant industry and regulatory experience.

We represent clients at every stage of the appellate process, including:

  • Briefing and arguing appeals
  • Advising on appellate matters
  • Interlocutory appeals
  • Petitions/applications for rehearing
  • Mandamus proceedings
  • Writs of certiorari
  • Amicus briefs

We excel in analyzing lower court proceedings and developing the strongest possible arguments for appeal. Recognizing that appeals can be won or lost due on the strength of the appellate brief, we work diligently to develop the arguments that are most likely to resonate with the appellate judges. All in all, our insight and skill, honed over the course of many years, give our clients every opportunity to succeed in appellate litigation. The following is one example of our firm’s appellate work:

  • Completion reversal and rendition on appeal of $204 million judgment entered against client in case tried by another law firm
  • Obtained favorable ruling from United States Court of Appeals for the Fifth Circuit in representation of foreign manufacturer against claims of trademark infringement, copyright infringement and unfair competition
  • Retained by other law firms to argue case before United States Court of Appeals for the Fifth Circuit, seeking affirmance of dismissal of case by the court below for lack of subject matter jurisdiction, with case affirmed by Fifth Circuit on appeal in favor of client
