The watchdog's report published in July spoke of how Saudi women are "boxed in" by laws which require them to seek the approval of a male guardian for the most simple transactions and activities, including travel, renewing a passport or going to work.
According to the report, which is based on interviews with 61 Saudi men and women, the system also locks women into abusive relationships without possibility of escape.
HRW contend that guardianship requirements are "the most significant impediment to realising women's rights in the country, effectively rendering adult women legal minors who cannot make key decisions for themselves".

"How come it's fair an old 50 yo women need her own son's permission to work/travel/get a treatment etc...?" asked Twitter user Haneen, referring to the fact that adult women in the kingdom often have their own children as guardians.
Other users used the opportunity to share videos of local religious scholars spewing their own views on how women, among other things, should be kept as "hostages" in their homes.
