It is a bit unclear why that version says "omitted". The Indian Legislature has a copy of The Representation of the People Act, 1951, where in the Arrangement of Sections listing it says "168. [Repealed.]", and the content of that section is
- [Special provisions with respect to Rulers of former Indian States.] Rep. by the Rulers of Indian States (Abolition of
Privileges) Act, 1972 (54 of 1972), s. 4 (w.e.f. 9-9-1972).
We would need to know your source for that text to understand why it says "Omitted" in your Contents section. In the Abolition of Privileges Act, §4
the text reads "Section 168 of the Representation of the People Act, 1951, shall be omitted". §43-44 of the 1951 Act was also eliminated by The Representation Of The People (Miscellaneous Provisions) Act, 1956, and is also currently listed as being "Repealed". The text of the 1956 act says
- Removal of disqualifications.- (1) Every disqualification for membership of Parliament or of the Legislature of a State incurred by
any person under the Representation of the People Act, 1951 (43 of
1951 ) (hereinafter referred to as the principal Act) before the
commencement of the Representation of the People (Second Amendment)
Act, 1956 , (27 of 1956 ) for failure to lodge a return of election
expenses as required by clause (c) of section 7 of the principal Act
is hereby removed.
(2) Every disqualification for membership of Parliament or of the
Legislature of a State or for voting at an election incurred by any
person under the principal Act before the commencement of the
Representation of the People (Second Amendment) Act, 1956 , for any
illegal practice or for any corrupt practice, other than the corrupt
practice of bribery or undue influence is hereby removed.
You might look at your version of the law to see what it says about §43-44 (repealed? removed? omitted?). It appears to not be legally significant, and probably arose by the codifiers who assembled the codified version of the various acts (who also added the footnotes). Presumably at one point it was decided to write "omitted" in the contents to match the wording of the repealing act, but the current version uniformly identifies repealed sections as "repealed", when the wording of the particular act means "this is repealed".
