Question juridique clé
Whether the son's hockey activity was predominantly professional already from 1 July 2003, ending entitlement to the child pension.
Solution extraite
Yes. The hockey engagement was professional and predominant from that date, so entitlement did not continue until 31 December 2004.
Motifs extraits
The training obligations, match schedule, travel and related commitments left insufficient room for systematic university studies. Enrollment alone did not prove real study efforts.
