The Decision Review System was again under the spotlight after the opening morning of the third Investec Ashes Test at Emirates Old Trafford.
Australia reached lunch at 92 for two but were left aggrieved after Usman Khawaja was given out by third umpire Kumar Dharmasena caught behind off Graeme Swann.
Khawaja almost immediately reviewed on-field umpire Tony Hill's decision to give him out and the Hot Spot technology appeared to back him up with no mark on the bat.
Dharmasena saw things differently, though, upholding the on-field call after a lengthy delay, in a decision branded "shocking and ridiculous" by former Australia leg-spinner Shane Warne in commentary.
The incident overshadowed opener Chris Rogers' progress to a career-best unbeaten 67, during which time the 35-year-old also passed 20,000 first-class runs.
England were unable to make a breakthrough in the opening hour as Australia progressed to 47 without loss.
After Michael Clarke elected to bat after winning the toss, the England bowlers did find some early movement.
Stuart Broad snaked the ball past Shane Watson's defences from consecutive deliveries while Rogers squirted a couple of boundaries away backward of point.
Rogers was surprisingly the more fluid of the openers and produced the shot of the first hour when he pushed James Anderson through a vacant mid-off for four.
England attempted to coerce an uncharacteristically circumspect Watson out of his shell with the opener loosely driving at a wide-ish Broad ball just short of point.
As the opening stand passed 50, England skipper Alastair Cook swung Anderson around to the Statham End, but Rogers greeted the move with three fours from the over to reach his half-century from 49 balls.
England got the breakthrough in the 17th over when Tim Bresnan found just enough seam movement to find Watson's edge as he pushed forward.
Cook pouched the simple chance at first slip but the controversy of the morning soon followed.
Khawaja played his part in his downfall, thrashing needlessly at a wide ball that turned further from Swann, but he appeared to have reason to feel aggrieved.
Dharmasena watched over the visual images before sending the batsmen on his way to prompt condemnation from not only Warne but also former England skipper Michael Vaughan, who tweeted: "And people say you should Walk....No chance when you get decisions like that.... #Ashes".
