Super Over to be used in semis, final

A Super Over will be used to decide the winners of the Champions Trophy semifinals and final in case of a match ending in a tie. 

Following a tied match, if the weather conditions prevent the Super Over from being completed, or if the match ends in no result, then the Group winners will progress to the final. In the event of a tied final, the teams shall compete in a Super Over to determine the winner.

And if the weather conditions prevent the Super Over from being completed, or if the match ends in no result, the teams will be declared joint winners. The Super Over tie-breaker was introduced in one-dayers during the 2011 World Cup, but it was not used as no knockout match ended in a tie after the regulation period.
