哈迪阿旺
Early reaction to the proposal was mixed. Both DAP secretary-general Lim Guan Eng and PAS president Abdul Hadi Awang welcomed the move, with Abdul Hadi's party voicing interest in the type of ink used. PKR vice-president Tian Chua initially remained sceptical unless the EC "implemented the system". Members of BN were more critical, with UMNO secretary-general Mohd Radzi Sheikh Ahmad, MCA secretary-general Ong Ka Chuan and Gerakan vice-president Teng Hock Nan proposing the use of other systems, such as a fingerprint-based biometrics system, as alternatives. An additional comment by BN against the use of the indelible ink was the lack of assurance the ink used will contain safe or halal ingredients, taking into account Muslim voters. On 9 August, the National Fatwa Council declared the ink safe for use, after receiving a lab report from the Chemistry Department of Universiti Kebangsaan Malaysia.
