Master Short recently conducted an exhaustive review of the principles of proportionality in discovery. In Warman v. National Post (2011), 103 O.R. (3d) 174 (S.C.J.), the defendant brought a motion seeking production of a mirror copy of the plaintiff’s computer hard drive. The action was a libel action brought under the Simplified Procedure.
Master Short held that the new rules changing the test from “relating to” to “relevant to” a matter in issue signal a shift away from the broad and liberal discovery practice that has existed in Ontario. The default rule should start with proportionality and a recognition that not all conceivably relevant facts are discoverable in every case. Master Short adopts an eight factor proportionality test for e-discovery used in an American case (Rowe Entertainment v. William Morris):
1. The specificity of the discovery requests;
2. The likelihood of discovering critical information;
3. The availability of such information from other sources;
4. The purposes for which the responding party maintains the requested data;
5. The relative benefit to the parties of obtaining the information;
6. The total cost associated with production;
7. The relative ability of each party to control costs and its incentive to do so;
8. The resources available to each party.
Master Short held that although relevancy should remain a threshold requirement, proportionality should replace relevancy as the most important principle guiding discovery.
This decision will no doubt garner attention as a guideline for discovery. It will be interesting to see if the eight factors become the new standard for discovery in general or limited to e-discovery.
