"(d) A member may decrease the amount credited to the member's operating account under this section by filing a written statement with the Committee on House Administration that specifies the amount of the reduction and the month the reduction takes effect. A member may revoke a statement previously filed with the Committee on House Administration only with the permission of the Committee and upon the filing of a written request with the Committee that specifically revokes the earlier statement. A committee chairman may file a statement reducing a committee's operating budget or a revocation of a previously filed statement in the same manner as an individual member under this subsection. The Committee may not deny a request made under this subsection unless granting the request would result in the member's or committee's operating account to have a negative balance that is not permitted under Section 5.045. The amount of reduction requested by a member shall be forwarded to the comptroller to the credit of the general revenue fund.
