Prima facie is a Latin term meaning at first look, or on its face, and refers to evidence before trial which is sufficient to prove the case unless there is substantial contradictory evidence shown at trial. A prima facie case must be presented to Grand Jury by the prosecution in order to get an indictment.
Prima facie evidence of a fact, is in law sufficient to establish the fact, unless rebutted. For example, when buildings are fired by sparks emitted from a locomotive engine passing along the road, it is prima facie evidence of negligence on the part of those who have the charge of it.
