If at any time the unemployment compensation fund, including the trust fund, clearing account and benefit account, and excluding therefrom an amount, estimated by the commissioner, equal to the sum of the benefit liabilities then accrued and unpaid, shall fall below the sum of $5 million, the commissioner, with the concurrence of a majority of the advisory council, and with the consent and approval of the Governor, may suspend the right to receive benefit for periods of partial unemployment not then completed, and no right to benefit for periods of partial unemployment completed or occurring during the period of such suspension shall then or thereafter accrue. At any time subsequent to such suspension the commissioner, with the concurrence of a majority of the advisory council, and with the consent and approval of the Governor, may rescind, and whenever the unemployment compensation fund, including the trust fund, clearing account and benefit account, and excluding therefrom an amount, estimated by the commissioner, equal to the sum of the benefit liabilities then accrued and unpaid, reaches the sum of $10 million, the commissioner shall rescind such suspension as to periods of partial unemployment not then completed.
