Terms can be implied in the following circumstances about the custom and trade usage problem?

Question

I would like to ask anyone why the terms can be implied in thefollowing circumstances about the custom and trade usage?
Furthermore, I would like to know that the British Crane Hire Corp Ltd V Ipswich Plant Hire Ltd case in 1974, could anyone give me in this case, thank you very much.

Answer 1

The basic idea is that if the contract is not specific about certain terms -- either the contract is considered defective and void -- or the court will allow the parties to fill in terms.

And for contracts between merchants -- industry custom and standard trade usage is how most things happen -- so it keeps contracts flowing smoothly to allow those assumptions.
