A by-election was held on 26 January 2019 for the Dewan Rakyat seat of Cameron Highlands. The seat became vacant after the Election Court on 30 November 2018 declared the incumbent Barisan Nasional (BN) Member of Parliament of Malaysian Indian Congress (MIC) Dato' Sivarraajh Chandran's victory in the seat null and void because it was found that corrupt practices were committed in the 14th general election. The court found Sivarraajh guilty of bribing of between RM30 and RM1,000 to the Orang Asli community voters prior to the election as established beyond reasonable doubt in the election petition filed by the Democratic Action Party (DAP) candidate M. Manogaran.
