And the first of the precedents we will see next month.
Were: For all athletes - quarantine for 2 years. Or the national federations could reach an agreement, and the quarantine period could be canceled.
For athletes <23 years - no changes. But if the biathlete wants to return to the mother country, he/she can do it without quarantine.
For athletes >23 years - Quarantine period - 3 years. And biathlete must provide evidence for IBU, that something connects with a new county (like family, husband/wife, roots). But national federation also can negotiate.
And rules for all: Biathlete can change nationality just once per career.
We will see how to easy it was for Russian Olga Podchufarova, and is it possible for Avvakumova, who was in Russian team and Korea team, and now wants to join Serbia.
