That argument is a non-sequiter, because "the requirements needed to make him eligible" are the issue that is under dispute.
Consider the irrationality of that argument . . .
Justice Department Official: "Mr. Landlord, we've determined that you have engaged in a long-term effort to refuse to rent apartments to minority applicants."
Landlord: "That's preposterous! How can you possibly say that?"
Official: "We've documented 150 cases in the last two years of prospective minority tenants with no criminal records, flawless credit reports, etc. -- all of whom were rejected. This is a clear case of systemic discrimination against minorities."
Landlord: "This apartment building has a written policy of renting only to white applicants. We didn't discriminate against any of those 150 applicants -- We simply turned them down because they didn't meet our written policy!"
