Construction Law/Invalid Instruction; Unauthorised Person


Dear Florin

Invalid Instruction; Unauthorised Person

We are a sub-con (NSC material supply) and we received an instruction from the Main Con’s Materials Mgr., via email, to procure 1m USD of extra Materials.

The NSC states
“instructions in writing [only]from “Superintending Officer…”
We maintain that the instruction is not valid.

Are we correct?

Dear Martin,

Thank you for your question.

If as a general behaviour you have often received other orders from that specific person (different from the “Superintending Officer…”), or whoever else from the Main Contractor and always these orders were recognised and paid, then in case of trouble, you can always demonstrate in court that although your contract indicates the “Superintending Officer…”, it has become a pattern to have orders from whoever and hence the "true will of the Parties" was for the Main Contractor to sort out among themselves the responsibilities and allow orders to be issued by no matter who.

But if that is not the case and suddenly you got an instruction from someone else, without having a written consent from the Main Contractor, then you better ask for a confirmation from the “Superintending Officer…”.

Strictly contractually speaking, yes, you are right, under described contract provisions, that instruction is not valid.

Hope that answer your question.
