Strictly the can is unnecessary, as it's entailed in the will; anything one will do one by definition can do, while not everything one can do one will do.

We have a policy of doing...

While one would obviously hope that people would not have a policy of doing things they had no right to do, in a context of stating different people's rights in a given situation, it's worth emphasising.
