In 2010, Havilio left his position at the Jerusalem Municipality, for reasons related to his relationship with Mayor Nir Barkat.

Havilio offered his services pro bono as a legal advisor to various organizations, and to represent public petitioners in the Supreme Court.

In one of his cases, Havilio petitioned the Supreme Court to allow the Cinema City complex in Jerusalem to stay open on Shabbat and Jewish holidays.

[7][8] From this petition, it was determined that the 130 million New Israeli Shekels that were in the Prazot fund would be used to purchase apartments for those entitled to public housing in Jerusalem.

[11] In 2014, Havilio founded Tzahor,[12] an organization that promotes equality, social and legal justice, human rights, and proper governance in Jerusalem.

[21] Since beginning his term in July, Havilio has focused on local environmental causes, increasing women's representation, simulating community co-ops, and addressing the needs of the Arab population.

In addition, Havilio's main focus is to represent the voice of the secular, liberal, and Traditional community in the very Orthodox and Haredi dominated Municipality.

The election, originally scheduled for the end of October 2023, was delayed to January 2024, then February 27, 2024, due to the breakout of the Israel–Hamas war.
