As @Mitch has pointed out in his comment to the question, there is considerable discussion about the expression Please do the needful here.
The answers there, however, discuss two - what I consider to be different - meanings for that expression:
Do the necessary or Do what is needed.
I consider this to mean Take the appropriate action to achieve the required result.
For example (quoting @ManishSinha, the author of the linked question):
"Please do what we expect you to do in this situation without being provided a detailed explanation"
"For example, a project manager gets a mail from marketing or quality assurance about something missing or incomplete, then he/she sends a mail to the subordinate with the body "Please do the needful". The subordinate is usually more well-versed with the work which has to be done. It might be his/her expertise so the manager might not tell what exactly needs to be done as is left upon him/her to figure out."
Do what's right or Do the right thing.
The expressions in the line above are also quoted from the author of the linked question, but (to me) those expressions mean something different from my first meaning.
I always considered these expressions to refer more to 'etiquette' or 'politeness'. This is not a case of 'taking the appropriate action to achieve the desired end', but a case of responding in the socially accepted 'polite' manner.
So, in my view, the answer to your question actually depends on its usage is India. Can it mean both of the above, or only one of the above?
