There are lots of exceptions where heresay CAN be admitted. You'd have to be MUCH more specific.
Under certain conditions hearsay can be admitted, Google for "dying declaration" and "res gestae" for examples.
And in California it can be accepted in preliminary exams if the officer has met the training requirements.
