842. Transitional Provisions and Qualifications
As of 1 July 2020, Athletes and Horses retain any star level qualification and successful completions that they had achieved as at 30 June 2020. They will be deemed to have completed the qualification requirements for their star level under these Endurance Rules.
The qualification requirements for Championships set out in Article 836 will not apply to any Championships being held in 2020, and so will apply only to Championships held from 1 January 2021 onwards. The qualification procedure for Championships set out in the 2019 edition of the endurance rules (see article 816.3) will apply to Championships held in 2020 (the FEI will issue a guidance document to assist in explaining the qualification criteria for the remaining 2020 Championships).
Athletes and Horses who have successfully completed a CEI 2* or CEI 3* together in combination since 30 June 2018 will be deemed to have qualified to compete as a Combination at the CEI 3* level for a period of two years from 1 July 2020.
