 Teams that toured other countries often became frustrated by lbws given against them ; there was often an assumption of national bias by home umpires against visiting teams . Several studies investigating this perception have suggested that home batsmen are sometimes less likely than visiting batsmen to be lbw . However , the data is based on lbw decisions awarded , not on the success @-@ rate of appeals to the umpire . Fraser points out that it is impossible to determine from these studies if any of the decisions were wrong , particularly as the lbw law can have different interpretations , or if other factors such as pitch conditions and technique were involved . A 2006 study examined the effect that neutral umpires had on the rate of lbws . Although the reasons were again ambiguous , it found that lbws increased slightly under neutral umpires regardless of team or location .
