E/C.12/1994/13 page 4 continue, there is the risk that [persons with disabilities] may increasingly be relegated to the margins of society, dependent on ad hoc support." 12/ As the Committee has previously observed (General Comment No. 3 (Fifth session, 1990), para. 12), the duty of States parties to protect the vulnerable members of their societies assumes greater rather than less importance in times of severe resource constraints. 11. Given the increasing commitment of Governments around the world to market-based policies, it is appropriate in that context to emphasize certain aspects of States parties’ obligations. One is the need to ensure that not only the public sphere, but also the private sphere, are, within appropriate limits, subject to regulation to ensure the equitable treatment of persons with disabilities. In a context in which arrangements for the provision of public services are increasingly being privatized and in which the free market is being relied on to an ever greater extent, it is essential that private employers, private suppliers of goods and services, and other non-public entities be subject to both non-discrimination and equality norms in relation to persons with disabilities. In circumstances where such protection does not extend beyond the public domain, the ability of persons with disabilities to participate in the mainstream of community activities and to realize their full potential as active members of society will be severely and often arbitrarily constrained. This is not to imply that legislative measures will always be the most effective means of seeking to eliminate discrimination within the private sphere. Thus, for example, the Standard Rules place particular emphasis on the need for States to "take action to raise awareness in society about persons with disabilities, their rights, their needs, their potential and their contribution". 13/ 12. In the absence of government intervention there will always be instances in which the operation of the free market will produce unsatisfactory results for persons with disabilities, either individually or as a group, and in such circumstances it is incumbent on Governments to step in and take appropriate measures to temper, complement, compensate for, or override the results produced by market forces. Similarly, while it is appropriate for Governments to rely on private, voluntary groups to assist persons with disabilities in various ways, such arrangements can never absolve Governments from their duty to ensure full compliance with their obligations under the Covenant. As the World Programme of Action concerning Disabled Persons states, "the ultimate responsibility for remedying the conditions that lead to impairment and for dealing with the consequences of disability rests with Governments". 14/ II. MEANS OF IMPLEMENTATION 13. The methods to be used by States parties in seeking to implement their obligations under the Covenant towards persons with disabilities are essentially the same as those available in relation to other obligations (see General Comment No. 1 (Third session, 1989)). They include the need to ascertain, through regular monitoring, the nature and scope of the problems existing within the State; the need to adopt appropriately tailored policies and programmes to respond to the requirements thus identified; the need to legislate where necessary and to eliminate any existing discriminatory legislation; and the need to make appropriate budgetary provisions or, where
