* If referring to the laws as a proper noun (specific laws with official names), then yes, capitalize them. For example, "The Individuals with Disabilities Education Act (IDEA)" or "Section 504 of the Rehabilitation Act." These are specific legal titles and should be capitalized like any proper noun.
* If referring to special education laws in a general sense, then no, do not capitalize. For instance, "Special education laws vary from state to state," or "The purpose of special education laws is to ensure..." Here, it's a generic reference, not a specific named law.
In short, treat it like any other proper noun. If it's a specific named law, capitalize it. If it's a general reference to the subject of special education laws, don't capitalize it.
