Born in Brussels, Belgium, Cesar Muniz Fernandez became interested in refereeing at the age of 16. Although he was busy internationally he was demoted from category 2 to 3 in 2011, but that category was changed to 2 6 months later. Hah!
Muniz Fernandez had his debut as a referee in the Segunda Division in 1997 and in the Primera Division in 2000. He received his FIFA badge in 2007 at the age of 37.
