There are no specific regulations prohibiting a former finalist (or even a former laureate) from competing in (or even winning again) the GPE more than once. The Philippine Madrigal Singers (laureate of the 1997 GPE) have won the 2006 "Florilège Vocal de Tours", going on to win the Grand Prize in 2007 in Arezzo, Italy. In the same competition, the Madrigal Singers competed with the Vesna Children's Choir (laureate of the 2000 GPE), who won the grand prize of the 2006 Tolosa competition.
