The series of proposals, presented by the first opposition government elected in Mexico's history, touched on some of the nation's most sensitive problems, and were so far-reaching that many would require Constitutional changes.

Like many of the groundbreaking proposals Fox made after defeating the party that has ruled Mexico for 71 years, some could be too ambitious to accomplish.

The proposals were made by a committee Fox formed just after his July 2 election, and it was not clear how many of them Fox actually planned to push before Congress. But Fox, who listened carefully as the committee announced its conclusions, had entrusted the group with his agenda, and many of their recommendations are themes he has already taken up.

The 175-member committee recommended a constitutional ban on using soldiers for peacetime policing or anti-drug work, areas where the army currently is an important part of day-to-day operations.

The committee also called for a national debate on abortion, which is currently illegal in Mexico, and the creation of a mechanism by which a president can be impeached.

The group also suggested allowing Mexican congressmen to stand for re-election, saying the decades-old ban on immediate re-election has resulted in a crop of inexperienced legislators with each new Congress, weakening the legislative branch.

Legislators also would be asked to drop an article of the constitution that allows foreigners to be expelled arbitrarily, and establish a "Truth Commission," which would investigate past human-rights abuses and corruption - but not punish them.

It is "the biggest and most ample collection of suggestions regarding policy decisions of the country that has been put together" since the 1910-1917 Mexican Revolution, Porfirio Munoz Ledo, the committee leader, told local news media before the announcement.
