Louis Brandeis, Benedict v. Ratner — Opinion of the Court
“ It does no more than to substitute the mortgagor as the agent of the mortgagee to do exactly what the latter had the right to do, and what it was his privilege and his duty to accomplish. It devotes, as it should, the mortgaged property to the payment of the mortgage debt.' The permission to use the proceeds to furnish substitute collateral 'provides only for a shifting of the lien from one piece of property to another taken in exchange.' Brackett v. ”
