The petition, which declares the selection of Dayan as ambassador as a "violation of the international legitimacy and sovereignty of Brazil," was sent to Brazil's president with the demand to reject, demanding that the government reject Dayan's appointment.
A few members of the Brazilian parliament have joined the condemnations and described the step as a challenge to Brazilian sovereignty and the country's official diplomatic positions – which view Israeli settlements in the West Bank as illegal under international law. The members of parliament labeled the appointment as an "attack on Brazilian diplomacy."
According to diplomatic protocols, after the Israeli government officially confirms Dayan's appointment, it will send the Brazilian government a request to approve the appointment as well.
Theoretically the Brazilian government reserves the right to reject the appointment; however this would be seen as a very unusual move, which is only reserved for the most extreme cases in which an appointment harms the host nation's national interest.
Prime Minister Benjamin Netanyahu announced Dayan's appointment a mere three weeks ago.
Brazil, a large South American nation with a population of 200 million, is the seventh largest economy in the world. Israel views the creation of strong economic and trade ties with South America, and Brazilian markets specifically, as of the upmost importance. The country is also home to a growing population of over 40 million Evangelical Christians who support Israel.
Dayan, 59, served as the head of the Yesha council in the years 2007-2013, and dealt with hasbara activities in Israel and abroad on a daily basis.
Officials in the Foreign Ministry responded to the petition saying: "We have no doubt that at the end of the process, including the Israeli government's official approval of the appointment, and the request for confirmation from the Brazilian government, Dayan will usher stronger ties between the countries. His appointment expresses the special importance Israel places on its relations with its friend Brazil."
