Handball is a dynamic team sport game in which a series of actions can take place in a short period of time and in a small space, without the human eye being able to follow it. The inertion of the human eye, in this case the referee's eye, can lead to numerous controversies related to the rules of the handball game. In the matches, everyone has the same goal, which is to beat the opponent, so they try to score a goal in every possible way, but because of that, there are two referees on the field who distribute justice. In this paper, the 'zero step' in open (matches) and closed (training) motor performance program was analyzed and an attempt was made to prove that it is not possible to simultaneously land on two feet, which significantly changes the rules of the handball game. The matches of the European Handball Championship 2024 held in Germany were analyzed in the matches that ended in a draw, and whether referee errors related to unjudged steps during the performance of the 'zero step' could have affected the final result. 18 senior players of the Kozala handball club, aged 16 to 24, participated in the research. For the purposes of the research, a motor task was composed in which, in the first phase, there was a jump to the 'zero step' from a standing position and a run, and in the second phase, a given feint and a shot at the goal. The results showed that no player jumped on both feet at the same time. A qualitative analysis of the matches of the European Championship in 2024 came to the conclusion that the final outcome could have been different, if there were no refereeing errors during the performance of the zero step. According to the obtained results, the anthropometric characteristics do not affect the difference in the time between the contacts of the left and right foot with the ground during the performance of the closed structure of the 'zero step' from the initial stance and from the take-off.
