You may be able to respond legally. It does depend on the nature of the inappropriate conduct, although the disability may have, say, prompted or motivated the inappropriate conduct. A disability in of itself, as much as a challenge as that may be to an individual, will not necessarily excuse inappropriate behavior, but it certainly would need to be taken into consideration or should be taken into consideration in terms of how the matter is handled.
A school can overlook a person's rights that have a disability, including the rights under the American with Disabilities Act, the ADA, section 504 of the Rehabilitation Act. You can't depend on the school to do the right thing. Even if something inappropriate did take place, the question would be, how should it be handled?
You need to have an experienced attorney advisor to help protect your rights and interests because you can't depend on the school to do so. They should be involved as early as possible in the process. They can help you understand and navigate the process.
