Can an advisory board extend the period of preventive detention for more than three months without reporting their opinion?
No, an advisory board cannot extend the period of preventive detention for more than three months without reporting their opinion. The context specifically states that no law providing for preventive detention shall authorize the detention of a person for a longer period than three months "unless...an Advisory Board has reported before the expiration of the said period of three months that there is in its opinion sufficient cause for such detention."
