1When the recognition of material evidence or other items related to the criminal offence is needed, the proceeding authority shall act in compliance with the rules for recognition of persons to the extent they are applicable.
2After finding out, where possible, at least two similar things to the one to be recognised, the proceeding authority shall ask the person called to make the recognition whether he recognises any of them and, if yes, invite him to state which of them he recognises and to specify whether he is sure.
3The recognition method is indicated in the minutes, under penalty of invalidity.
