Basically, it calls for a Boycott of Israel, Divestment from Israel, and Sanctions on Israel, due to its apartheid policies in the occupied Palestinian territories (settlement expansion, imprisoning Palestinians in occupied territory, etc.) till it complies with international human rights laws and respects the rights of Palestinian citizens of Israel, lets Palestinian refugees return, and ends its long-time occupation of Palestine.
