The client wants to use the domain that has the duplicate site. Shouldn't we refrain rom 301 redirecting it because it's "tainted"?
Dupe content doesn't "taint" a domain. Dupe content gets filtered, not penalized.
By redirecting the second domain to the main domain as g1smd suggests, you eliminate the dupe problem.
And since the first domain is already the one that's coming up for searches, and it's older and more established, redirecting the second domain to the first one is a better choice than redirecting the first to the second.
