Google states it will “remove reviews that represent personal attacks on others.”  Thus, in the event of a false review that targets an individual or individuals from a business, this is a possible avenue (although this still will likely require presenting a court order to Google).

Second, a business representative can flag a review as inappropriate and hope that Google will determine there to be a policy violation and, accordingly, remove the review.  Factoring in the countless requests Google receives daily, a business probably should not assume that simply flagging a review will lead to defamation removal.
