Is there a presumption that a lawyer subject to a lateral transfer received relevant confidential information?

As already indicated, an unrebutted presumption that a lawyer subject to a lateral transfer received relevant confidential information gives rise to a concomitant presumption of risk that it will be prejudicially used. The second question, or “branch” as counsel puts it, of the test in Martin v. Gray asks if the presumption of that risk is also unrebutted.
