Brunei: what is the penalty for polygyny without permission?

In Brunei, marrying again without permission is an offence under s.123 Chapter 217: a fine of up to $2,000, imprisonment of up to 6 months, or both. Section 23(1) forbids a man from marrying another woman "in any place" while his marriage subsists except with the written permission of a Syar'ie Judge. If he marries without permission, the marriage may only be registered subject to s.123, that is, after action for the offence. Chapter 217 also makes a husband's failure to treat a wife justly according to Hukum Syara' an offence (s.129), and a false declaration to the Registrar is also an offence (s.126), each with the same maximum penalty. Marrying abroad to avoid the court process does not help. See Brunei.
