Election pendulum

The 14th General Election witnessed 20 governmental seats and 16 non-governmental seats filled the Negeri Sembilan State Legislative Assembly. The government side has 11 safe seats and 1 fairly safe seat, while the non-government side has 3 safe seats and 3 fairly safe seats. In addition, there were 1 seat that win uncontested in non-governmental seats; namely Rantau (won by incumbent assemblyman, Mohamad Hasan).

Aftermath

Rantau seat nomination dispute

Rantau constituency incumbent assemblyman and Barisan Nasional candidate Mohamad Hasan won his seat uncontested after People's Justice Party (PKR)’s candidate Dr Streram Sinnansamy was not allowed to enter the Nomination Centre to file his papers by the Election Commission (EC), supposedly because he did not have in his possession a pass issued by the Election Commission.^[8][9] However, the Election Court has on the 16 November 2018, allowed the petition by Dr S. Streram and passed a ruling that Mohamad Hasan had not been duly elected, subsequently nullified Hasan's result.^[10] A by-election was then held on 13 April 2019 after Mohamad Hasan's appeal was dismissed by the Federal Court on 18 February 2019. Mohamad Hasan somehow emerged victorious and managed to retain his seat again.^[11]
