What must be proven to establish a breach of duty in professional negligence?

To establish a breach of duty in professional negligence, it is essential to provide evidence of deviation from established professional standards. This means that the individual or entity being accused of negligence failed to meet the level of care that is accepted by their profession, which is typically determined by what a reasonably competent professional would have done in similar circumstances.

In professional negligence cases, the plaintiff has the burden to demonstrate that the professional’s actions did not align with these accepted standards, which is crucial because it underscores the expectation of a minimum level of competence in the respective profession. For example, a medical professional is expected to follow the practices and procedures that other practitioners in the field would consider appropriate and adequate under the specific circumstances of the case.

The focus is on the professional's conduct relative to established norms rather than emotional reactions, compliance with the lowest standards, or merely having awareness of community practices. Each of these aspects serves different purposes in legal analysis but does not directly speak to the necessary element of showing that the professional did not act in accordance with what is widely accepted in their field. Therefore, the strongest and most relevant proof for a claim of professional negligence is demonstrating a deviation from recognized professional standards.
