The question is: is this assumption well founded? Assuming that the Presidential Order had suspended the citizens ' right to move any court for enforcing their fundamental rights under articles 14, 21 and 22 and had made 835 the said Order applicable to persons detained under the of 1950, could that Order have effectively prevented the detenues from contending that their detention was illegal and void? In such a case, if the detenu was detained under the of 1950 and he challenged the validity of his detention on the ground that the relevant provisions of the said Act had not been complied with, would his challenge be covered by article 359(1) and the Presidential Order issued under it? In other words, can it be said that in making the said challenge, he was enforcing his fundamental rights specified in the Presidential Order? If it is held that he was challenging the validity of his detention because the mandatory provisions of the Act had not been complied with, his challenge may be outside article 359(1) and the Presidential Order.
