A bill seeking to exempt five states from the exercise to redraw constituencies was approved by the Lok Sabha on Tuesday night amid acknowledgment by government that there were "some mistakes".
Law Minister H R Bhardwaj said the government has gone by consensus as it could only accept or reject the recommendations of the Delimitation Commission.
Referring to all-round complaints from members on the manner in which their constituencies were redrawn, Bhardwaj said in the future it would be better if MPs have a greater say in the exercise as bureaucrats do not contest elections.
He said not much attention was paid to detail when the Delimitation Act was passed by Parliament in 2002.
The minister said the decision to put on hold the delimitation process in five states was taken as there was great dissatisfaction among the tribals as many seats reserved for them were being converted to general seats.
