Social Security Organisation procedures set by central government: meetings, authentication, validity despite vacancies, and member allowances. Section 9 empowers the Central Government to prescribe meeting intervals, procedures and quorum for Social Security Organisations and Committees; mandates authentication of orders and decisions by specified or authorised senior officers; protects acts and proceedings from challenge solely due to vacancies or defects in constitution; and provides that members are entitled to fees and allowances as prescribed by the Central Government.
