An interim injunction has been granted to 15 Iban longhouse communities in upper Sebangan in Simunjan, Sarawak, ordering Quality Concrete Holdings Bhd and its contractor Loyal Billion Sdn Bhd to halt logging, land clearing and other related activities there.

Timber concession licence holder Quality Concrete is substantially owned by Sarawak Chief Minister Taib Mahmud's sister, Roziah. Another two of Taib's family members also have shares in the company.
