Born in
Nieuwpoort, Marteel now lives in
Gijverinkhove. He first qualified as a referee in 1994, and began refereeing on the main professional tour in 2006. He took charge of his first
World Snooker Championship final in
2015, becoming the first Belgian to referee a world final, and the second referee from continental Europe to do so, after
Jan Verhaas. Marteel refereed his second world final in
2022. In addition to the World Championships, Marteel has officiated the
Masters final three times, in
2016,
2018, and
2025, and the
UK Championship final three times, in
2016,
2020, and
2025. He also plays snooker, and has achieved highest breaks of 133 in practice and 78 in competition. He worked in the frontline as a nurse in Belgium during the
COVID-19 pandemic, despite being trained as a radiologist. In the
2023 World Snooker Championship, he prevented a
Just Stop Oil protester from gluing herself to the table; this occurred moments after another protester had covered the opposite table in orange powder. The match overseen by Marteel resumed shortly after the interruption, while the other match was delayed to the next day. ==References==
