The AFL is likely to come under scrutiny for a polarising score review decision in the third quarter of Fremantle's clash with Geelong in Friday night's semi final.
Cats winger Ollie Dempsey appeared to execute a bicycle kick goal from the square but it was ultimately ruled a behind.
The arc determined that there was insufficient evidence to overturn the umpire's decision of a touched behind.
The vision appeared to show the ball coming off the Fremantle defender's forearm onto Dempsey's boot, but the arc seemingly determined the contact was simultaneous and it was ruled a behind.
It comes after the league spruiked new goal line technology which arrived ahead of finals providing the arc with a clearer view and more frames per second in slow motion replays.
