Referees Oleksii Derevynskyi and Dmytro Panchyshyn (involved in the erroneous penalty appointment against Oleksandriia in the Ukrainian Championship match against Rukh) underwent an interview procedure on a lie detector. This was reported by the Telegram channel "TaToTake".
The source informs that, according to preliminary results, polygraph specialists found no signs of bias in either referee in any form. Everything indicates that the mistakes were a result of human error.
Recall that Derevynskyi (now as on-field referee) awarded an erroneous penalty in the 4th round UPL match Rukh — Zorya.
