Whenever the committee deems that it will increase the salability or the price of the bonds to obtain, prior to or after sale, a legal opinion, other than that of the Attorney General, as to the validity of the bonds, the committee may authorize the State Treasurer or the Department of Finance, or both, to obtain such a legal opinion. Payment for such legal services shall be made from the proceeds of the sale of the bonds, or any other funds available to the authority with respect to bonds authorized pursuant to Section 3940 or the commission with respect to bonds authorized pursuant to Section 3950.
