The group is referring to 17 U.S.C. Section 1201 of the Digital Millennium Copyright Act,(the "DMCA"), which purports to make it unlawful to override a CD or DVD's digital copyright protection even if the copying of the copyrighted material is legitimate, non-infringing fair use.
Nevertheless, I'm not sure a court could impose liability under Section 1201 of the DMCA on someone who evades DRM protection on a CD or DVD if the copying is for a fair use. Fair use is founded in the Constitution, both in Article I, Section 7, which gives Congress the power to "promote the progress of science and useful arts, by securing for limited times to authors and inventors the exclusive right to their respective writings and discoveries," and in the First Amendment protection of free speech. In other words, fair use is a constitutional right, and constitutional rights cannot be derogated by legislation.
I'm not so sure. Congress cannot through legislation deprive someone of using material in a way the First Amendment of the Bill of Rights and Article I, Section 7 of the Constitution permit. Thus, I am confident, a statute that makes it unlawful to copy for fair use purposes any document stating "no copy of this document is permitted by its author for any purposes" would be unenforceable under the Constitution. I do not see why DRM protection, which can generally be cracked very easily, should, for fair use purposes, be treated any differently than such a bare declaration that any copying is unlawful.
