A member of the Democratic Turnhalle Alliance (DTA), de Waal was a member of the National Assembly of Namibia from 1994 to 2010. De Waal was placed third on DTA's electoral list ahead of the 2009 general election but lost his seat in the National Assembly after DTA received enough votes for 2 legislators.
