Parliament having their first session is irrelevant IMO.  They cannot work on passing the budget until they receive it.  Sudani’s GOI has not passed it yet.  All laws, including the budget, have to pass the GOI prior to Parliament receiving them.  It is only then that Parliament can commence the First Reading.  Thereafter, it goes to the relevant Committee to discuss, review and then return to Parliament with their analysis and comments.  The Second and Third Readings can then commence. If passed, it can then be sent to the President for signature.  After which, it then goes to the Finance Minister for disbursement which often takes upwards of 30 days.
