61. Subject to section 60, non-beneficiaries are not authorized to reside on Category I lands except in virtue of the by-laws of the interested band or, as the case may be, of the interested Cree village corporation.
Such by-laws must authorize non-beneficiaries to reside on Category I lands if, with the approval of the local government, they are engaged in administrative or public duties or in scientific studies, provided that such activities do not require the presence of a number of persons sufficient to significantly alter the demographic composition of the Cree community.
