Practicable

On the difference between practical and practicable.

“Practicable” means feasible: able to be done or successfully put into practice:
“Practical” means useful: “the door to the hen-house came of its hinges but, fortunately, Our Bill is quite practical and he jury rigged some chicken wire and an electromagnet, and the chooks don't go near it now”.

In a legal document, one generally means “practicable”, and will see it in tiring and emotive phrases like “all reasonably practicable steps”. Of course you could always use “feasible”, but that would spoil the fun somewhat.
