Hello,
Section 12 of the ID Act describes the duties of the Conciliation Officer. Section 12(3) specifically talks about a settlement reached in the course of Conciliation proceedings. So, a settlement reached before the Conciliation Officer is generally referred to as a 12(3) settlement. Please see the relevant section below:
Section 18 is all about the applicability of settlements and awards. Section 18(1) talks about the applicability of the settlement between two parties. So, a settlement reached between two parties without intervention is referred to as an 18(1) settlement. Please see the relevant section below:
Section 18(3) is about the applicability of the settlement arrived at before the Conciliation Officer and awards. These settlements are applicable to all:
I presume when you said a settlement arrived at 18(3), you meant before the Conciliation Officer. It is referred to as a 12(3) settlement. This settlement will be applicable to all workmen, present and future.
