June 10 (Reuters) - A California state court judge denied

motions by Meta Platforms ( META ) and Google's

YouTube seeking a new trial after a jury found them

liable for designing social media platforms that are harmful to

young people, sources familiar with the ruling confirmed on

Wednesday.

Los Angeles Superior Court Judge Carolyn Kuhl ruled on the

motions on Tuesday, according to court documents. The order

stating her ruling and explaining her reasoning was not

immediately available.

The companies had sought a new trial after a jury found them

negligent and imposed a $6 million in damages.
