OConnell Scott

Scott O'Connell

Scott O’Connell is a trial attorney and litigation strategist focused on complex commercial disputes involving high financial and reputational exposure. He has considerable experience leading class action and aggregate litigation as well as parallel government enforcement and regulatory proceedings, most notably involving health service, financial service, energy or manufacturing companies. He has been lead counsel on more than 60 trials, arbitrations, evidentiary injunction proceedings and related appeals in federal and state courts around the country. Scott provides clients with customized and value-driven strategies for resolving cases on their terms.

According to Chambers USA—in which he has been recognized for more than a decade: “The ‘wicked smart’ Scott O’Connell ‘is an enormously talented litigator and an expert on courtroom procedures,’ interviewees confirm. He is particularly skilled in contentious banking and finance matters, as well as issues arising for health care industry clients.” In addition to multiple, other third-party professional recognitions, Best Lawyers® has named Scott “Lawyer of the Year” seven times since 2013 for health care, securities, banking and finance, bet-the-company and appellate litigation.

In addition to an active practice, Scott served as chair of Nixon Peabody’s 325+ person Litigation Department. He also was a member of the firm’s management and compensation committees.  He maintains an active docket of pro bono cases specifically related to the prevention of domestic violence and providing needed access to justice. Scott received the Frederick Douglass Human Rights Award from the Law Office of the Southern Center for Human Rights for successful representation and ultimate release of a Guantanamo Bay detainee in the case Rimi v. George W. Bush, United States District Court for the District of Columbia, No. 1:05-CV-02427.

What do you focus on?

I currently focus my practice in the following areas of financial and reputational exposure:

Trials, Arbitrations and Evidentiary Proceedings

Telling compelling stories with effective witnesses and evidence is at the heart of trial advocacy. Taking complex commercial disputes and breaking them down into thematic and compelling narratives is what I strive to do. I have had the privilege to do trial and evidentiary hearings around the country for different clients in various subject matters. This is my passion and is indeed the best part of my job.

Class Action, Mass Torts and Aggregate Litigation

Class actions are costly and disruptive because they attack products, services and business processes. The exposure can be substantial. I work closely with businesses to find and implement solutions that limit accruing exposure while also defending the case.

Crisis Intervention, Internal Investigations and Parallel Proceedings

Catastrophic events, health and safety issues or corporate integrity matters can destroy a company. Intervening quickly to manage the parallel criminal, regulatory and civil proceedings as well as the challenges presented by social media is essential to restore the brand. I have considerable experience counseling companies through these types of emergent situations.

Health Service Reimbursement Litigation

Many health service providers deliver considerable uncompensated care. These services have material negative financial impacts on these institutions. I counsel these providers with regard to reimbursements owed from Medicaid, Medicare and third-party payors. This work involves federal and state litigation as well as Administrative Procedures Act challenges.

Constitutional Claims

Representation of individuals, business entities and political organizations in the defense of constitutionally-protected rights and liberties. I have developed a particular focus on protecting against the impairment of contracts through state action.

Domestic Violence Protection (Pro Bono)

Practicing law is a privilege, not a right. With that privilege comes professional responsibilities. I consider providing pro bono service one of my professional responsibilities. As someone who grew up experiencing domestic violence, I devote time annually to helping abused spouses and children secure orders of protection and related assistance to remove violence from the home. It should not “hurt” to be a child and part of my commitment is to help those suffering escape the hurt.

What do you see on the horizon?

Managing parallel proceedings is like playing three dimensional chess. Coordinating between criminal, regulatory and civil proceedings is not a linear process. Decisions in one sphere can have material impacts in another. Having a legal team able to identify these threats and navigate successfully through them is essential to mitigate risk and protect your company. Make sure that the team you use is able to operate simultaneously in these different forums.

Social media adds a level of complexion to these parallel proceedings. Brand protection in high exposure litigation is very challenging. Now more than ever, a company needs to be ready to defend itself in the court of public opinion long before a court of law. This is a radically different mindset for most defense minded attorneys who want the luxury of time and analysis to consider options. Legal teams need to be nimble, strategic and very conversant with the brand objectives for your company. If you lose the brand, there might not be anything left for which to fight in the parallel proceedings.

Containing annual litigation spend is an essential task for both in-house and outside counsel. On this topic, your outside legal team is not simply a service provider but a business partner to address these issues. I work closely with clients to develop strategies and fee agreements to maximize value. Utilizing project management tools, effective and disciplined implementation of case specific strategies, and risk sharing compensation models all help to contain cost and maximize value. Using alternative fee agreements which migrate from compensation based on straight billable hours to risk/reward models best aligns your interest with your outside team. Asking your attorneys to share some of the risks and rewards ensures that value, efficiency and success are always driving the development of your case. Asking your outside team to have some “skin in the game” is itself a game changer.
