New York Legal Malpractice Lawyer: a Case Study on Expert Witness Negligence

Medical malpractice cases almost always require expert testimony to establish both deviation and causation, unless the alleged negligence falls within common knowledge. 

In this matter, the original attorney chose not to retain a board-certified neurologist, believing that the medical records and factual timeline were sufficiently clear.

While attorneys are afforded discretion in strategic decision-making, courts recognize that certain types of proof are legally required. 

The absence of expert testimony in a specialized neurological injury case created a substantial evidentiary gap.
 

At trial, the court determined that the plaintiff failed to establish a prima facie case. 

Without expert testimony linking the provider’s conduct to the neurological injury, the causation element could not be satisfied. The action was dismissed.

Following dismissal, the client consulted a New York legal malpractice lawyer to determine whether the failure to retain an expert constituted a departure from professional standards.
 

The Court of Appeals in Rudolf v Shayne, Dachs, Stanisci, Corker & Sauer, 8 NY3d 438 (2007), reaffirmed that an attorney may be liable where the client can prove that, but for the attorney’s negligence, the underlying action would have succeeded.

Legal malpractice is not established merely because a strategy fails. 

However, where expert testimony is legally necessary to establish a prima facie medical malpractice case, a complete failure to secure such testimony may fall below the standard of reasonable professional skill.
 

New York courts generally avoid second-guessing reasonable tactical decisions. 

The distinction turns on whether the attorney exercised professional judgment within accepted norms.

In this matter, the New York legal malpractice lawyer argued that proceeding to trial without any expert in a complex neurological malpractice action was not a strategic choice within professional norms but rather a failure to satisfy a basic evidentiary requirement.
 

Under Rudolf and subsequent decisions such as Nomura Asset Capital Corp. . Cadwalader, Wickersham & Taft LLP, 26 NY3d 40 (2015), the plaintiff must establish proximate causation through proof that a favorable outcome would have been obtained absent counsel’s error.

This requires more than speculation; it requires evidentiary reconstruction of the original claim.
 

To meet this burden, the New York legal malpractice lawyer retained a qualified neurologist to review the medical records. 

The expert opined that the healthcare provider deviated from accepted standards of neurological care and that the deviation directly caused the injury.

This testimony demonstrated that the underlying case was legally viable and that the dismissal stemmed from the absence of required expert proof rather than from a lack of substantive merit.
 

Damages in legal malpractice actions are generally measured by the value of the claim that was lost. 

The New York legal malpractice lawyer reconstructed the projected recovery in the medical malpractice action, including medical expenses, lost earnings, and pain and suffering.

The court assessed whether the reconstructed damages were supported by competent expert testimony and whether the client would have likely obtained a favorable verdict.
 

In appropriate circumstances, a plaintiff may also recover legal fees paid to the negligent attorney if those fees were proximately caused by the malpractice. 

However, such recovery is not automatic and depends on proof of causation and actual loss.

The court ultimately determined that the client had been deprived of a meaningful opportunity to recover substantial compensation due to the failure to present legally required expert testimony.
