The center, which describes itself as an independent consultancy dedicated to find a solution for the Palestinian refugees in accordance with international law, has denied the Israeli allegations. It announced last Friday that it was starting legal action against Israel's UN Mission for alleged defamation.
Last month, the UN committee that accredits non-governmental organizations, or NGOs, recommended that the center's application be approved.
But Israel circulated a resolution, co-sponsored by the United States, Australia and Canada, to the committee's parent body, the 54-member Economic and Social Council known as ECOSOC, opposing the application for consultative status.
Israel's Deputy UN Ambassador David Roet said before the vote that the center "is not what it claims to be."

Roet said world media sources, intelligence agencies and independent researchers have cited numerous links between the center and Hamas, which controls the Gaza Strip. He called the center "an essential part of the Hamas network in Europe," that recruits, radicalizes and encourages operatives to take up arms against Israel.
The center says it has been operating in Britain and Europe since 1966 and specializes "in the research, analysis, and monitor of issues pertaining to the dispersed Palestinians and their internationally recognized legal right to return."
US Deputy UN Ambassador Michele Sisson said the center only applied for consultative status a year ago and the United States has "serious concerns" about its background and activities that haven't been answered.
