As South Africa, we hosted the World Cup in 2010.
Upon the insistence of FIFA & in accordance with the Host Country & Host City Agreements, we had to waiver laws, by-laws, policies, regulations, processes & the like, to ensure that South Africa became the ultimate hosts of the world during the period.
We passed special legislation specifically to meet FIFA's hosting requirements for the 2010 World Cup. The most important were the '2010 FIFA World Cup South Africa Special Measures Act, 2006 (Act 11 of 2006)' and the 'Second 2010 FIFA World Cup South Africa Special Measures Act, 2006 (Act 12 of 2006)'. These laws were enacted to give legal effect to the guarantees we had made to FIFA during the bidding process.
The special laws effected temporary special provisions & exceptions in certain areas, including: Special visa, work permit, & accreditation arrangements for players, officials, media & visitors.
These requirements were not exclusive to South Africa, as Korea & Japan (2002), Germany (2006), Brazil (2014), Russia (2018), Qatar (2022), had to enact the same.
