the applicable legal requirements of the country concerned. This exception is also incorporated directly into certain national regulations which govern the club-level teams from that country, as shown by regulation 9.14.2.1 of the Irish Rugby Football Union: The following are the registered players who are eligible to play in the All Ireland League and Cup: (i) A Player who qualifies to play for Ireland under World Rugby Regulations. (...) Association football (soccer) In association football, this rule can be found at the international level in the statutes of the Fédération Internationale de Football Association (FIFA), in articles 6 and 7. The former states: if, in addition to having the relevant nationality, he fulfils at least one of the following conditions: a) He was born on the territory of the relevant Association; b) His biological mother or biological father was born on the territory of the relevant Association; c) His grandmother or grandfather was born on the territory of the relevant Association; (...) Note that unlike World Rugby, which now substitutes adoptive parents for birth parents in determining national team eligibility, FIFA continues to use only biological relations for this purpose. Among the most notable countries to have availed of the "granny rule" is the Republic of Ireland, where the wide spread of the Irish diaspora left large numbers of potential recruits, especially in the United Kingdom. Jack Charlton (manager 1986–96) was especially noted for recruiting English-born footballers who had Irish ancestry. Many German-born players who have Turkish ancestry have chosen to play for Turkey. This is partly due to Germany's strict rules on dual citizenship which forces German-Turks to choose whether to have German or Turkish citizenship by the age of 23 (in accordance with the German Citizenship Law of 1999). Baseball and softball The World Baseball Softball Confederation (WBSC), which governs both baseball and softball internationally, requires nationality as a precondition for national team selection, but does not mention the grandparent rule in its bylaws. The method by which a player obtains legal nationality is irrelevant to national team eligibility, at least from the WBSC's perspective. The relevant bylaw uses the language "country or territory", thereby encompassing both fully sovereign states and dependent territories. Basketball FIBA, the international governing body for basketball, has eligibility rules largely similar to those of the WBSC. Nationality is a precondition for national team selection, and the grandparent rule is generally not employed. The
