What is misfeasance?

Misfeasance refers to the improper performance of a lawful act. This means that even though the action being carried out is legal and permissible, the person executing it does so negligently or incompetently, resulting in harm or injury. It highlights the difference between acting when one should not (nonfeasance) and acting incorrectly despite having a legal right to do so.

In the context of athletic training, a trainer may make a decision that, under normal circumstances, is considered appropriate, such as administering first aid. However, if that first aid is administered poorly or without proper technique, resulting in further injury or complications, that would be classified as misfeasance. This underscores the importance of not only knowing how to perform a task but doing so with the appropriate standards and care.
