What standard of care is that of a reasonably competent lawyer in the conduct of litigation?

The trial judge was correct to state that in the conduct of litigation the standard of care is that of a reasonably competent lawyer and that a judgment call in the course of litigation that could reasonably have been made by a reasonably competent lawyer in similar circumstances will not amount to negligence even if it is proven later that a different position would have produced a better result (at para.8, and see Meister v. Coyle, 2010 NSSC 125).
