Please help me to explain the grammar of this sentence belows:

I don't undersand how to use "be" after directors " authorized by the Directors be and is/are hereby authorized". Please help me

Solution 1:

We really need more context. I suspect the cited text isn't really an "independent sentence". For example, perhaps it's one of several "bullet points" listed under some context-setting initial text, such as The Board of Trustees are agreed that...

...in which context subjunctive ...that the Directors be authorized [to blah blah] is perfectly okay, as is ...that the Directors are authorized [to blah blah].

Both verb forms represent "performative utterances", in that making the statement is equivalent to providing the authorization - same as, for example, I [hereby] promise to tell the truth.
