6. Material is not cumulative

The United States District Court for the District of Colorado applied Silkwood's four-factor test in Re/Max Int'l Inc. v. Century 21 Real Estate Corp., 846 F. Supp. 910 (D. Colo. 1994). Century 21 brought a variety of claims, including unfair competition, based upon Re/Max's nationwide advertising campaign. A local newspaper published an article discussing Re/Max's challenge to Century 21 to determine who was the best real estate company. Century 21 subpoenaed the reporter merely to authenticate statements appearing in the article. The Court quashed the subpoena because Century 21 failed to show the information sought was substantially relevant to a central issue in the case, and that the information could not be obtained from other reasonable sources. The evidence sought from the reporter -- to confirm that published statements had been uttered by a previous witness in the case, to impeach his deposition testimony -- was also deemed cumulative of other evidence in the record.
