Which of the following IS a defense against pecuniary liability?

Following established procedures serves as a defense against pecuniary liability because it indicates that the individual acted in compliance with the rules and guidelines set forth by their organization or governing body. This demonstrates a commitment to the processes designed to mitigate risk and ensure that actions taken are within the bounds of accepted practice. Adhering to established protocols not only protects the individual from claims of negligence but also reinforces their due diligence in making decisions that could impact financial outcomes.

In contrast, neglecting to follow procedures, taking spontaneous action without documentation, and ignoring previous rulings and guidelines suggest a disregard for established protocols. These actions can lead to mistakes or oversights that may result in financial liability, as they reflect a failure to act reasonably or responsibly in a professional context, which the law often scrutinizes in liability cases. By highlighting the importance of following established procedures, the correct response emphasizes the essential role of adherence to guidelines in protecting against financial repercussions.
