Tort law is a branch of civil law that deals with civil wrongs (other than breach of contract) that cause harm or loss to another party, resulting in legal liability for the person who commits the tortious act. In this scenario, the regulated member publicly posted negative comments that allegedly harmed the competitor's business reputation and sales. This action falls under a specific type of tort known as "defamation" (specifically "libel," since it is written/published online). Even if the member believes they were justified, making public statements that damage another organization's financial standing without utilizing proper regulatory or legal channels exposes the member to a civil lawsuit for damages. Furthermore, the ASET Code of Ethics requires members to conduct themselves with fairness and courtesy toward clients, colleagues, and others. Publicly smearing a competitor online is not only a potential tort but also highly unprofessional conduct.
