This is why I love my legal education:

The MEATLOAF test.

Because I WOULD DO ANYTHING FOR LOVE, BUT I WON'T DO THAT which does not fulfill the following criteria.

1. Measure taken must be invited by the other party (Consent)
2. Measure taken must be reciprocated (Consideration)
3. Measure taken must be reasonable and proportionate to the expected outcome (Balancing test)

There is a context to this I swear.
