Collin J. LeBlanc handles complex civil litigation matters involving industrial, casualty and premises liability claims, legal malpractice, insurance coverage and subrogation disputes, and other difficult cases. In addition to his trial and appellate practice, Collin often helps businesses as in-house counsel for employment, liability and contracts matters.  
He has trial experience in several states and in the state and federal courts of Louisiana.  He is known for his early, well-reasoned assessment of a matter. In many cases, this strategic approach leads to a resolution of the dispute for his clients without the expense and distraction of costly litigation. Consistent with this focus, he maintains a heavy motion practice with an eye to an early execution of the litigation plan.
Collin regularly works with legal and technical experts, including engineers, business loss, vocational rehabilitation, and wage experts.  In the highly complex insurance and industrial cases he handles, he has worked with and argued against experts in the following disciplines:
  • Safety
  • Accident
  • Reconstruction
  • Toxicology
  • Medical causation
  • Business valuation
  • Legal standards of care
In defending legal malpractice claims, he has gained significant exposure to many different areas of law and underlying legal concepts.
Additional practice:
  • Subrogation

Representative Experience

  • Recently, successfully tried and won legal malpractice suit alleging six-figure exposure.
  • Conducted a trial of exceptions leading to dismissal of a high-exposure case in a maritime setting.
  • Argued or drafted double-digit successful motions for summary judgment leading to full dismissal in the last few years, including in substantial 18-wheeler litigation, premises liability and other areas.
  • Litigated a jury trial recouping all amounts paid by client in an oilfield-related incident.
  • Consulted with dozens of businesses concerning their rights following Deepwater Horizon disaster.
  • Worked with a liability carrier to handle a real estate closing matter, where a bank sued its lawyer for being unaware of a loan.
Appellate advocacy is also a consistent part of Collin's practice.  Representative cases include:
  • Reeves v. Structural Preservation Systems,731 So.2d 208 (La. 1999). In Reeves, he wrote the winning brief in what became the seminal Louisiana decision for the determination of when a work-related accident can lead to tort exposure.
  • MB Industries LLC v. CNA Insurance Co., 74 So.3d 1173 (La. 2011). In MB Industries, his effort helped to convince the Louisiana Supreme Court that a legal malpractice claimant must possess an active duty to mitigate their damages. Legal malpractice claimants must now appeal an adverse ruling when a reasonable person would have done so or risk a dismissal of their claim. The decision also required competent "standard of care" expert opinions in non-evident malpractice leading to a dismissal of his client in a case with seven-figure exposure.
