28 CFR Part 35 Nondiscrimination on the Basis of Disability in State and Local Government Services (1991 ADA Title II Regulations)

Paragraph (b)(1)(v) provides that a public entity may not aid or perpetuate discrimination against a qualified individual with a disability by providing significant assistance to an agency, organization, or person that discriminates on the basis of disability in providing any aid, benefit, or service to beneficiaries of the public entity's program. This paragraph is taken from the regulations implementing section 504 for federally assisted programs.
