SOCHI, Russia -- Argentine skier Maria Belen Simari Birkner has lost her legal bid to compete at a fourth Olympics alongside her sister and brother.
The Court of Arbitration for Sport says it had no jurisdiction to judge an appeal by Simari Birkner against her non-selection on Jan. 20 by Argentina's Olympic team and ski federation.
A CAS panel says its Olympic authority began Jan. 28, though Simari Birkner's case "would have failed" on it merits.
The court says she alleged discrimination "on the basis of her family affiliation."
Simari Birkner's sister Macarena and brother Cristian Javier are both competing in Alpine races at the Sochi Olympics wearing vivid black and white polka-dot race suits.
Cristian Javier Simari Birkner carried Argentina's flag at the opening ceremony.
