The word ‘evidence’ includes all the legal means which will prove or disprove any matter of fact which is submitted to judicial investigation. Evidence, in juristic sense in the case of oral testimony of witnesses is that the party against whom it is used has the right of cross-examining the witnesses.
In legal terminology, ‘Evidence’ means and includes all statements which the Court permits or requires to be made before it by witnesses, in relation to matters of fact under inquiry. These are known as oral evidence. It also includes all documents produced for the inspection of the Court which is known as documentary evidence.
The rules of evidence are in general the same in civil and criminal proceedings and are applicable in a similar manner to State and citizen, prosecutor and accused, plaintiff and defendant, counsel and client.
It is a well settled principle of law that relevant evidence can be taken into account irrespective of the method by which it is obtained.
