 (4) The deposit of any moneys forming part of the Consolidated Fund with a bank or with the Crown Agents for Overseas Governments and Administrations or the investment of any such moneys in securities in which, under the law for the time being in force in Botswana, trustees are authorized to invest, or the making of advances to such extent and in such circumstances as may be prescribed by Parliament, shall not be regarded as a withdrawal of those moneys from the Fund for the purposes of this section. 119. Authorization of expenditure   (1) The Minister for the time being responsible for finance shall cause to be prepared and laid before the National Assembly, before or not later than 30 days after the commencement of each financial year, estimates of the revenues and expenditure of Botswana for that year.  (2) The organisations of expenditure contained in the estimates for a financial year (other than expenditure charged upon the Consolidated Fund by this Constitution or any other law) shall be included in a Bill to be known as an Appropriation Bill which shall be introduced into the Assembly to provide for the issue from the Consolidated Fund of the sums necessary to meet that expenditure and the appropriation of those sums for the purposes specified in the said Bill.  (3) If in any financial year it is found-  (a) that the amount appropriated by the Appropriation Act for the purposes included in any organisation of expenditure is insufficient or that a need has arisen for expenditure for a purpose for which no amount has been appropriated by the Appropriation Act; or  (b) that any moneys have been expended on any organisation of expenditure in excess of the amount appropriated for the purposes included in that organisation by the Appropriation Act or for a purpose for which no amount has been appropriated by the Appropriation Act, a supplementary estimate showing the sums required or spent shall be laid before the National Assembly and the organisations of expenditure shall be included in a supplementary Appropriation Bill, or in a motion or motions approving such expenditure, which shall be introduced or moved in the Assembly.  (4) Where any supplementary expenditure has been approved in a financial year by a resolution of the National Assembly in accordance with the provisions of subsection (3) of this section, a supplementary Appropriation Bill shall be introduced in the National Assembly, not later than the end of the financial year next following, providing for the appropriation of the sums so approved. 120. Authorization of expenditure in advance of appropriation   Parliament may make provision under which, if the Appropriation Act in respect of any financial year has not come into operation by the beginning of that financial year, the President may authorize the withdrawal of moneys from the Consolidated Fund for the purpose of meeting expenditure necessary to carry on the services of the Government until the expiration of four months from the beginning of that financial year or the coming into operation of the Appropriation Act, whichever is the earlier. 121. Contingencies Fund   (1) Parliament may make provision for the establishment of a Contingencies Fund and for authorizing the President, if satisfied that there has arisen an urgent and unforeseen need for expenditure for which no other provision exists, to make advances from that Fund to meet that need.  (2) Where any advance is made from the Contingencies Fund, a supplementary estimate shall be laid before the National Assembly as soon as possible for the purpose of replacing the amount so advanced.
