relevant to its legality and its actual operation would seem to be within the ambit of the opportunity to be heard that is embraced within the concept of due process, at least until the issue has been resolved to the contrary.
The Court suggests that landlord-tenant law raises no federal questions. This is not quite so clear to me. We have held that the right to complain to public authorities is constitutionally protected. In re Quarles, 158 U. S. 532. If a defendant in an FED action is denied the right to assert as a defense the claim that he is being evicted, not for the nonpayment of rent, but because he exercised his constitutional right to complain to public officials about the disrepair of his apartment, a substantial federal question would be presented. See Edwards v. Habib, 130 U. S. App. D. C. 126, 129-137, 397 F. 2d 687, 690-698 (1968).
The Court also implies that to find for appellants in this case, we would have to hold, as a matter of constitutional law, that a lease is required to be interpreted as an ordinary contract. But this is not at all necessary. Oregon has already adopted the modern, contractual view of leasehold analysis. The issue that confronts the Court is not whether such a view is constitutionally compelled, but whether, once Oregon has gone this far as a matter of state law, the requirements of due process permit a restriction of contract-type defenses in an FED action. Cf. Shapiro v. Thompson, 394 U. S., at 627 n. 6; Sherbert v. Verner, 374 U. S. 398, 404-406.
Normally a State may bifurcate trials, deciding, say, the right to possession in one suit and the right to damages in another. See Bianchi v. Morales, 262 U. S. 170; American Surety Co. v. Baldwin, 287 U. S. 156.
But where the right is so fundamental as the tenant’s claim to his home, the requirements of due process should be more embracing. In the setting of modern urban
