THE proposed Bangsamoro Basic law (BBL) -- a measure that abolishes the existing Autonomous Region in Muslim Mindanao (ARMM) and replaces it with Bangsamoro Region – is constitutional and will be signed into law by President Rodrigo Duterte during his third State of the Nation Address (Sona) on July 23, members of Congress said on Monday.

Senate Majority Leader Juan Miguel Zubiri and Majority Leader Rodolfo Fariñas of Ilocos Norte at the House of Representatives made the announcement on the first day of discussions of the bicameral conference committee on the BBL.
