The case won't hinge on the letterhead issue (and we don't know what letterhead Dini actually used).
A publicly funded institution through its agent, a professor, cannot have a policy which overtly coerces a student to disavow his religious beliefs - or affirm a religious belief he does not hold.
Student as plaintiff.
Since the mid-seventies, it has been established that states (and their employees) can be sued for discrimination despite sovereign immunity. Fitzpatrick v. Bitzer.
If the DOJ intervenes with regard to equal protection, they may do it under 42 USC 2000h-2:
Student as plaintiff.
The student can bring a civil action for deprivation of rights under 42 USC 1983:
The DOJ may be involved under 42 USC 2000c-
(2) signed by an individual, or his parent, to the effect that he has been denied admission to or not permitted to continue in attendance at a public college by reason of race, color, religion, sex or national origin,
and the Attorney General believes the complaint is meritorious and certifies that the signer or signers of such complaint are unable, in his judgment, to initiate and maintain appropriate legal proceedings for relief and that the institution of an action will materially further the orderly achievement of desegregation in public education, the Attorney General is authorized, after giving notice of such complaint to the appropriate school board or college authority and after certifying that he is satisfied that such board or authority has had a reasonable time to adjust the conditions alleged in such complaint, to institute for or in the name of the United States a civil action in any appropriate district court of the United States against such parties and for such relief as may be appropriate, and such court shall have and shall exercise jurisdiction of proceedings instituted pursuant to this section, provided that nothing herein shall empower any official or court of the United States to issue any order seeking to achieve a racial balance in any school by requiring the transportation of pupils or students from one school to another or one school district to another in order to achieve such racial balance, or otherwise enlarge the existing power of the court to insure compliance with constitutional standards. The Attorney General may implead as defendants such additional parties as are or become necessary to the grant of effective relief hereunder.
(1) the role, if any, of such letters in the professor's official state-financed duties; I would add that the role of letters of recommendation in granting admission to medical school may be of interest to the DOJ or the court. That would go to damages from the students civil case and to public interest in the DOJs case.
(2) whether the professor's insistance on accepting evolution is commendable academic rigor, or actually constitutes a form of religious discrimination; and I dispute that will be an issue at all. The point is whether he can require an truthful affirmation of a theory which disavows ones cherished beliefs. The argument that cherished beliefs does not mean religion will be defeated on the basis of Dinis homepage, wherein I understand he declares a campaign against creationism and the fact that he is requiring an affirmation (an oath, like a loyalty oath) rather than statement of the theory.
(3) notwithstanding the answer to #2, the professor's freedom to use such a criterion -- acceptance of human evolution -- as a factor in his decision to recommend a biology student. The really big pdf file I linked yesterday from AAUP shows that the courts have ruled academic freedom is an institution right not an individual right and not a constitutional right. Personally, I think this kind of defense if not very carefully played - could anger the judge by leaving the impression that the professor thinks individual academic rights ought to supercede the constitution.
The best defense I have found for the university and the professor lies with state sovereign immunity. Historically, individual rights (equal protection in particular, but also freedom of religion) have weighed against immunity. But if ever there was a time to press for immunity, this would be it because this particular USSC, just this term, upheld the eleventh amendment vigorously in Federal Maritime Commission v. South Caroline State Ports Authority. The case did not have a fourteenth amendment issue, but it shows a desire on the USSC to uphold state sovereign immunity.
In this article, AAUP describes the meaning of the state sovereignty issue to professors as plaintiffs The Sleeper Amendment: Sovereign Immunity. But the same issues arise when the university is defendant in a suit brought by a student.
In this 2001 case a student sued a university for gender discrimination by a professor Hayut v. State University of New York (U.S. District Court, New York, 2001)
As for the kid, Im still hoping somebody will remind him about I Cor 6:1-8. Creationists (to my knowledge) believe as I do that the Bible is the inerrant Word of God and thus if he cannot truthfully affirm on that tenet, then he should also stand down on I Cor 6:1-8 (especially now we know that Dini is Catholic. They may not agree on the interpretation, but they have the same Savior.)
"Any scientist who jumps beyond the scientific method to issue decrees on things not subject to observation or testing is overreaching."
