The UK high court will have to decide whether a card game bridge is a sport and should receive legal benefits.

The English Bridge Union (EBU), which has 55,000 members, argues that Sport England, the state body that allocates funding to non-professional sports associations, has a narrow definition of sport when it rejected an application in 2014 to recognize bridge as one.

Sport England said that to qualify as a sport under its rules, it says, an activity must have some kind of physical element.

“When ruling on what constituted a sport in the 2011 Charities Act, parliament specifically included ‘mind sports’, stating that sport comprised ‘activities which promote health involving physical or mental skill or exertion,’” said EBU spokesman. Adding “bridge required undoubted levels of mental skill” and had “known health benefits.”
