The move is seen as part of Ukraine's efforts to reinforce its army as soldiers struggle to hold positions against Russia
The Surrey opener had made 85 to set England on their way to an eventual eight-wicket win against Australia in Thursday's semifinal at Edgbaston, when he was given out caught behind down the legside by Dharmasena.
Roy requested a review but England had already used their lone review of the innings.
Nevertheless, Dharmasena incorrectly signalled for a review, with Australia pointing out his mistake.
Roy, his arms spread wide, clearly believed Dharmasena should have signalled a wide delivery instead and the audibly furious batsman had to be ushered away from the crease by square-leg umpire Marais Erasmus.
Replays suggested he did not touch the ball.
The England star, 28, was fined 30 percent of his match fee for showing dissent and received two demerit points from match referee Ranjan Madugalle.
That took his tally for the World Cup to three but match bans only kick in when a player collects four demerit points in total, leaving Roy available to feature on Sunday as England bid to win the World Cup for the first time.
The final game will be officiated by Kumar Dharmasena and Marais Erasmus. Rod Tucker, Aleem Dar and Ranjan Madugalle will also be officials for the game.
Dharmasena and Erasmus will be the on-field umpires.
Australian Rod Tucker will be in the third umpire's chair and Pakistan's Aleem Dar will be the fourth official.
The referee of the match will be Sri Lanka's Ranjan Madugalle.
