Oregon retailers cannot discriminate against gun buyers based on their age, according to a ruling this week by the Oregon Bureau of Labor and Industries.

Hannah Brumbles, an 18-year-old from Deer Island in unincorporated Columbia County, filed a complaint with the state after a Walmart store in St. Helen’s refused to sell her a rifle or ammunition in February because she was under 21.

Oregon law allows individuals 18 and older to purchase firearms, but a variety of regional and national retailers, including Walmart, adopted more restrictive policies following the mass shooting in Parkland, Florida, where former student Nikolas Cruz, 19, is accused of killing 17 people at Marjory Stoneman Douglas High School on Feb. 14.

Brumbles’ complaint said the policy was discriminatory and violated the Oregon Constitution. The state industry bureau found in her favor.

Brumbles is seeking damages for physical, mental and emotional distress, which could be as high as $5,000. A follow-up hearing will be held in November.
