Abstract:
The author considers that in practice of investigation there were always versions which had mainly accusatory
character and versions resisting to them, called by countercases (justificatory). The versions contradicting
each other can always take place in the conditions of competitive structure of criminal procedure. Versions of
defense are considered as a type of the forensic case, considering in addition to the subject of nomination one
more basis of classification — a functional and target sign. On this sign the author suggests to distinguish the
following types of forensic versions: investigative, expert, judicial, operational search, accusations and defense.
Possibilities of nomination of versions of defense by the lawyer defender are shown and the definition
of the case of defense is formulated.
