Representative Cases

Product Liability:

  • Successfully prosecuted numerous property damage files involving failed plumbing parts, including braided supply line failures, fractured plastic coupling nuts, failed plastic and brass angle stop valves, and other plastic and metal plumbing parts, securing reimbursement of paid damage claims.
  • Investigated property damage to determine cause and origin of the loss, including gas explosions and fire damage, placing necessary parties on notice of inspection, securing appropriate experts to assist with the investigation, and managing the initial inspection of the property.

Workers’ Compensation Subrogation:

  • Successfully secured almost a half million dollars in future credit from an automobile injury that left the claimant a double amputee; thereby minimizing payments by the worker’s compensation carrier.
  • Prosecuted multiple cases involving worker injury involving industrial machines and loss of limbs, securing reimbursement for worker’s compensation liens from responsible manufacturers.

However, in two recent decisions, this argument has failed. Article written by Aaron D. Plamann, published in Claims Pages on August 1, 2019.
