UNITED NATIONS (AP) — Once the Palestinians achieve their goal of an upgrade to nonmember observer state status at the United Nations on Wednesday, they face a series of struggles to capitalize on that recognition throughout the UN system.

The Palestinian Authority, which has the majority support needed in the General Assembly, would join the Vatican as the only other entity with nonmember observer state status after the body votes. In practice, the Palestinians gain few new powers.

Much of what unfolds will depend on how hard the Palestinians want to pursue membership in various agencies, and who will support them. Here’s a look at how the Palestinians’ role could change at the UN:

* The upgraded Palestinian Authority still won’t be able to introduce resolutions to the General Assembly. Like the Vatican, the Palestinians would have to find a sympathetic nation-state or bloc of nations in the Assembly to introduce any resolution — as they do now.

Last year, the Palestinians tried and failed to get full UN member-state status. The Security Council must approve new members, and the United States made clear it would veto any Palestinian attempt. So the doomed full membership bid was never brought forward for a full council vote.

* The International Court of Justice, often called the “World Court,” accepts only disputes between fully recognized member-states of the UN. In the past, countries that were not yet UN members — Switzerland and Nauru — accepted the jurisdiction of the court. However, parties to any dispute must be willing to accept the court’s judgment, and it is hard to imagine any case in which both Israel and the Palestinians would agree to be bound by the court’s decision.

* The International Criminal Court at the Hague can review war crimes, and Israel has objected to the possibility of the Palestinians bringing cases to the ICC. But to do so, the Palestinians would have to file papers of “accession” under the Rome Treaty that set up the ICC. That membership option is open to “all states.”

In practice, the application to become a “state” member of the ICC system would go to the office of the UN Secretary-General, which is the official repository for signatures. The UN chief’s office would, in that case, have to turn to the UN legal department for an opinion on whether the Palestinians constitute a “state.”

The Palestinian Authority tried to have alleged Israeli crimes in the 2008-2009 Gaza conflict investigated, but prosecutors in April refused to open an investigation, saying it was not clear if the Palestinians qualified as a state and that only states can recognize the court’s jurisdiction.

* Among the UN’s array of other organizations, membership is largely dependent on agreement of the members of the body. Omar Awadalla, who oversees UN affairs at the Palestinian Foreign Ministry, said experts are already hard at work assessing which UN bodies they will be eligible to join. In general, the Palestinians would be able to successfully lobby for membership in any body or agency that mirrors the General Assembly in membership.

Officials believe that even as a nonmember state, the Palestinians could join influential international bodies such as the World Trade Organization, the World Health Organization, the World Intellectual Property Organization, the World Bank and the International Criminal Court.

While membership in some of these bodies would be largely symbolic, other agencies could provide a useful platform for the Palestinians. UNESCO admitted the Palestinian Authority to membership in 2011, and infuriated Israel by defining West Bank holy sites sacred to both Jews and Muslims as “Palestinian.”
