The Organization of American States, after a meeting last week in which a majority of members present spoke against the invasion of Grenada as a violation of 30 nations' principle of nonintervention, has failed to come up with a resolution on which to vote.

No action is expected before the annual OAS General Assembly of foreign ministers, opening here Nov. 14, and there is no assurance that the issue will be discussed then.

Bolivian Ambassador Fernando Salazar Paredes, who presided over the organization's Permanent Council meeting Wednesday, said, "I am sure the General Assembly will consider the issue." He said the assembly, which once was largely an administrative body, must now become a strong political body at a "tragic moment" for this oldest of regional organizations.

Declarations Wednesday showed 15 nations opposed to the invasion of Grenada, an OAS member. The United States and six Caribbean states involved spoke in favor, and six other nations indicated they would support no more than a reaffirmation of the principle of nonintervention. Suriname was not present, nor was Cuba, which renounced membership years ago.

Asked which side had won, Salazar said, "We all have lost. . . . The OAS has lost because its principles are under challenge."

The council adjourned for "consultations" on a possible resolution.

The recent influx of small Caribbean states into the OAS has become a factor in its seeming paralysis. A majority of the Latin American members could be expected to denounce any U.S. intervention, as they did in the Dominican Republic crisis of 1965.

Now even that issue has proven divisive. The OAS has come under increasing criticism for repeated failures to take substantive action in regional crises. It has played virtually no role in Central American conflicts. Member nations Colombia, Venezuela, Mexico and Panama, acting as the so-called Contadora Group, stepped outside the organization in their attempt to mediate among Nicaragua, Honduras, El Salvador and the United States.
