When hearing a witness following the entry into force of the Act on Criminal Procedure, the warning to witnesses must be communicated in conformity with the Act on Criminal Procedure, hence no warning can be made under the former Act on Criminal Procedure.
Where a witness has already been heard as a witness under the rules of the former Act on Criminal Procedure, at his repeated hearing held after the entry into force of the Act on Criminal Procedure, the warning to witnesses must be communicated to him in conformity with the new Act on Criminal Procedure.
Where a witness entitled to refuse to testify but not having refused to testify under the rules of the former Act on Criminal Procedure wishes to avail himself of this right and refuses to testify at his repeated hearing made after the entry into force of the Act on Criminal Procedure, his formerly given testimony shall not be used after the entry into force of the Act on Criminal Procedure.
