The author supports V.A. Musin's concept, that a full-fledged discovery of evidence has to be introduced in the Russian arbitration procedure law. This would ensure the compliance with the procedural rights of the parties to dispute, improve the stability and predictability of justice and prevent the forgery of evidence. The author analyses all possible sanctions for untimely discovery of evidence and concludes that the most effective one is considering such evidence impermissible and returning it to the party of the dispute. The author also shares his personal memories of Valeriy Abramovich Musin.
