It is against the law (ADA) to ask someone for a doctors note to prove a disability.
In fact, requiring that is grounds for a discrimination lawsuit.
You're not entirely correct. It is not against the law to ask for a doctor's note. It is against the law for an
employer to ask for a doctor's note (and in most cases medical records) for any reason other than to prove the need for a reasonable accommodation when a disability is not apparent, but enough about employment. That's for the EEOC to worry about.
However, you are absolutely correct that asking for a doctor's note to prove a disability in order to gain a service is grounds for a discrimination lawsuit under the ADA. In said lawsuit, the ADA, HIPAA, and other relevant state and local laws will be brought into the mix to show that this request is beyond reasonable. That is why you will not find a company who will ask for your medical records or a doctor's note, regardless of if you are handicapped. Just to be clear, I'm not taking about employment. That's an entirely different ball game.
One last time, I know that HIPAA does not directly forbid people from asking for medical records, but it is absolutely, 100% relevant in a hypothetical situation where records come into play, because in the (hypothetical) lawsuit, it will be used as grounds to
prove discrimination and unreasonable standards.
For your amusement, here's a portion of the ADA:
"
§ 36.201 General.
(a)
Prohibition of discrimination. No individual shall be discriminated against on the basis of disability in the full and equal enjoyment of the goods, services, facilities, privileges, advantages, or accommodations of any place of public accommodation by any private entity who owns, leases (or leases to), or operates a place of public accommodation."
And:
"§ 36.202 Activities.
(a)
Denial of participation. A public accommodation shall not subject an individual or class of individuals on the basis of a disability or disabilities of such individual or class, directly, or through contractual, licensing, or other arrangements, to a denial of the opportunity of the individual or class to participate in or benefit from the goods, services, facilities, privileges, advantages, or accommodations of a place of public accommodation.
(b)
Participation in unequal benefit. A public accommodation shall not afford an individual or class of individuals, on the basis of a disability or disabilities of such individual or class, directly, or through contractual, licensing, or other arrangements, with the opportunity to participate in or benefit from a good, service, facility, privilege, advantage, or accommodation that is not equal to that afforded to other individuals."
This part is relevant for the federal case and original post:
"(c)
Separate benefit. A public accommodation shall not provide an individual or class of individuals, on the basis of a disability or disabilities of such individual or class, directly, or through contractual, licensing, or other arrangements with a good, service, facility, privilege, advantage, or accommodation that is different or separate from that provided to other individuals, unless such action is necessary to provide the individual or class of individuals with a good, service, facility, privilege, advantage, or accommodation, or other opportunity that is as effective as that provided to others."
Anyways, I'm still sure we don't disagree on the point. They're not going to start asking for medical records or doctor's notes.
