Meaning of "Notwithstanding anything contained in this section"

When a clause begins with the word “Notwithstanding” the object is to give it overriding effect over other provisions of the sections/act ....... which is equivalent to saying in spite of those provisions the particular clause would have a full operation.

This in contradistinction to the phrase “Subject to” which conveys that the provision would yield to another provision.

Thanks for appreciation....

I humbly pass on the credits to Solicitor Parimal K Shroff & Adv. Ashok Mulgaonkar; who very well guided me in such matters.
