The maul changes have been controversial
The controversial rule change which led to the maul almost becoming extinct is set to be rejected by rugby chiefs.
An International Rugby Board conference has discussed the impact of the experimental law variations (ELVs) being trialled around the world.
After two days of review, 10 ELVs have been recommended to be passed into law.
But the variation allowing mauls to be pulled down was thrown out while the ELV which sees most offences penalised with a free-kick is to be reviewed.
Although the ELVs are believed to have boosted the amount of time the ball is in play, there have been concerns among many, particularly those in the northern hemisphere, that they have reduced the quality of attacking play.
The Rugby Football Union elite rugby director Rob Andrew and Lions coach Ian McGeechan have been critical of the ELVs.
The IRB conference - which featured coaches, referees, administrators and representatives from all the major unions - conducted a detailed review into the ELVs which were introduced worldwide in August 2008.
The review included statistics from more than 800 matches in 15 different countries.
One of the recommended ELVs is the pass-back rule, which prevents players from making any ground with a kick to touch if the ball has been played back into their own 22.
It was this rule, when Wales fly-half Stephen Jones kicked out on the full in the final game of the Six Nations, which gave Ireland the line-out for their Grand Slam-winning drop-goal in Cardiff.
Another recommendation is the five-metre off-side line at the scrum, a move that has proved popular with coaches.
However, some of the most contentious variations were not ratified by the London conference.
The ELV allowing mauls to be pulled down has been at the centre of much discussion with the likes of Ireland coach Declan Kidney and Italy boss Nick Mallett among the voices of dissent.
Italy have used the maul as an offensive weapon in the past but with opposing teams able to pull it down without sanction, they struggled without it and finished this year's Six Nations with the Wooden Spoon.
Chris Cuthbertson, chair of the Rugby Football Union's ELV Task group said: "The feedback from the Game and our game analysis indicates that pulling down the maul and unrestricted numbers in the line-out have not improved the game."
Meanwhile, the sanctions ELV, which sees most offences penalised with a free-kick and is currently being trialled in the southern hemisphere's Super 14 competition, has been sent away for further review.
Former Ireland coach Eddie O'Sullivan said the number of free-kicks now awarded in the Super 14 had led him to stop watching it.
The IRB is also looking to clarify the rules at the breakdown, which has seen teams less inclined to counter attack.
A complaint of this change has been that sides have instead traded downfield kicks for long passages of play.
"Naturally opinions differed in several areas of the ELV programme," IRB chairman Bernard Lapasset.
"The IRB regards this as a healthy and positive state of affairs as the game's laws have always and should continue to allow coaches and players to interpret law so that different styles of play can be employed.
"What was clear was that there was agreement on many aspects of the ELVs and a collective will to see a return to one set of laws to govern the game as soon as possible."
The IRB's rugby committee will finalise their list of recommendations at a meeting in Dublin on 27 April before putting it before the full IRB council on 13 May.
