Tucson might face litigation over the religious shrine on “A” Mountain.

The Freedom From Religion Foundation sent the city a second letter earlier this week asking the city reconsider its decision to leave the Lady of Guadalupe shrine on public property.

In the letter, FFRF attorney Patrick Elliott wrote countless past court cases offer immutable proof the city is on the wrong side of the constitution and should take it down.

“It would be wise to resolve the issue once and for all, rather than to maintain religious shrines that are a liability and affiliate the City with one religion,” Elliott wrote. “FFRF has pursued such violations in federal court and is considering its options in regards to the City’s actions.”

City attorney Mike Rankin said he will review the letter and respond accordingly.

FFRF originally asked the city to remove the shrine back in June.
