SAN JOSE, Costa Rica (AP) _ Former President Oscar Arias, who won a Nobel Peace Prize for helping bring peace to the region, says he would consider running again for Costa Rica's presidency if the constitution is amended to permit it.

``Various friends have approached me and have proposed the idea. I am going to consider it,'' Arias said in an interview broadcast Thursday night by local television Channel 7.

A constitutional amendment in 1969 barred re-election to the four-year presidential terms.

Some politicians have proposed modifying the constitution to allow former presidents to seek the office again after eight years out of power, though the proposal faces an uphill battle in the single-house legislature.

``It is not fair that a voter cannot vote for his favorite only because of the sin of having been elected president,'' Arias said. ``I know I would have the support of Costa Ricans.''

Arias won the Nobel Prize in 1987 for efforts to end Central America's guerrilla conflicts and at age 59 he remains popular.

Since leaving office in 1990, Arias has run a private foundation.
