this sign, and others similar to it, have been going up in East Jerusalem neighborhoods, including in the Shimon HaTzaddik neighborhood.

Interestingly, the sign stating the illegal occupation of the land references a UN decision from November 29, 2012. Nothing happened in the UN on November 29 that determined such illegality. All that happened was the upgrading of the status of the Palestinian non-member state's UN membership level. Sure, that decision is important and has ramifications, but it says nothing about the legal status of any specific parcel of land.
