Although res ipsa loquitur is frequently treated as a doctrine or rule of law, it is in fact nothing but a bundle of legal concepts, each of which may be treated separately. Unfortunately, the content of such a bundle varies so extensively from time to time and place to place that the general title "res ipsa loquitur" has little or no significance unless it is used with reference to a particular time and place, and sometimes also with reference to a particular field of law.
