The difference between the past and the present is that individual freedom and security no longer fall to be protected solely through the D vehicle of common-law maxims and presumptions which may be altered or repealed by statute, but are now protected by entrenched constitutional provisions which neither the Legislature nor the Executive may abridge. It would accordingly be improper for us to hold constitutional a system which, as Sachs J has noted, confers on creditors the power to consign the person of an impecunious debtor to prison at will and without the interposition at the crucial time of a judicial officer.
