The defendant admitted pinning up the posters in several mosques, saying he solely launched an “awareness campaign” after finding that some “female relatives were facing injustice at the hands of their families,” the daily said.
Thousands of Saudis signed in September a petition urging an end to the guardianship system following a Twitter campaign which the court claims was launched by the defendant.
Saudi Arabia has some of the world’s tightest restrictions on women, and is the only country where they are not allowed to drive.
Under the guardianship system a male family member, normally the father, husband or brother, must grant permission for a woman’s study, travel and other activities.
Activists say that even female prisoners have to be received by the guardian upon their release, meaning that some have to languish in jail or a shelter beyond their sentences if the man does not want to accept them.
