What Constitutional rights are you referring to?
Any and all.
Take the post above, about an agent wanting people to, conditional to receiving a permit, give up half of what they find. Such a thing would require people to waive their rights under, for example, the fourth amendment (the right to remain private in your affairs), the fifth amendment (the right to remain silent).
That aside, the above cite has been construed, in law, to mean should not be forced to waive one right conditional to accepting another. That is what is described, you must agree to something before you will be given something.
Hsieh v. Civil Service Commission of City of Seattle, 79 Wash. 2d 529, 488 P.2d 515 (Wa. 08/26/1971)
. . . .
[30] Jahn v. Seattle, 120 Wash. 403, 406, 207 P. 667 (1922). We there also took note of then extant United States Supreme Court cases upholding provisions regarding nonemployment of aliens on public work. Heim v. McCall, 239 U.S. 175, 60 L. Ed. 206, 36 S. Ct. 78, Ann. Cas. 1917B 287 (1915); Crane v. People of New York, 239 U.S. 195, 60 L. Ed. 218, 36 S. Ct. 85 (1915). However, see Graham v. Richardson, 403 U.S. 365, 29 L. Ed. 2d 534, 91 S. Ct. 1848 (1971), wherein, in referring to Heim and Crane, the Supreme Court stated: "But this Court now has rejected the concept that constitutional
