Sarawak is questioning whether the Petroleum Development Act (PDA) — the law that created Petroliam Nasional Bhd, Malaysia’s only Fortune 500 company and vested with the nation’s oil and gas wealth — is still relevant today.
The question hinges on the state of emergency under which the bill was passed in 1974, according to The Edge Malaysia‘s cover story ‘Why Sarawak questions the Petroleum Development Act’ for the week of Jan 29-Feb 4 by assistant editor Khairie Hisyam Aliman, citing the Sarawak Chief Minister (CM).
The CM Datuk Patinggi Abang Abdul Rahman Zohari, popularly known as Abang Johari, told the weekly that the issue is a critical matter Sarawak is actively pursuing.
