Andy Ruiz's ex has won her court battle with the star boxer ... TMZ Sports has learned a judge granted her a permanent restraining order earlier this month against the former heavyweight champ.
Julia Lemus had been seeking the order of protection since April 2023 ... after she alleged Ruiz sexually assaulted, abused, and terrorized her throughout their relationship.
In her application for the order, Lemus -- who began seeing Ruiz around 2016 -- said the 34-year-old would often grab and yank her to move her wherever he wanted her to go.
