Agency and Powers of Attorney — Union or Intersection?

It is well accepted that powers of attorney are a form of agency, and thus fall within a subset of the law of agency. This does not, however, justify the assumption that all aspects of agency law necessarily translate to the law governing powers of attorney. In several significant ways, not the least of these being the strict construction approach to construing powers of attorney, the general law treats powers of attorney discretely. By targeting the peculiar treatment of powers of attorney, outside the statutory arena, one can ascertain what makes the power of attorney a legal construct capable of standing, in some senses, on its own.
