I want to know the answer to the following question:
When is assent effective if the presiding officers inform their houses at different times?
All the background I'm provided with is that "This is important because, under British Law, unless there is any provision to the contrary, an act takes effect on the date on which it receives royal assent and that date is not regarded as being the date when the letters patent are signed, or when they are delivered to the presiding officers of each house, but the date on which both houses have been formally acquainted of the assent.". Is that enough to answer the question?
Answer: no
