Story highlights Supreme Court ruled parliament must vote to start Brexit

Miller received threats of rape and death over the case

Tune into CNN International's Amanpour show at 2 pm ET to watch Paula Newton's interview with Gina Miller.

London (CNN) She is the woman who took on the government and won. But Gina Miller, the London-based businesswoman behind a landmark Brexit legal challenge, has suffered months of threats and racially abusive trolling in the process.

On Tuesday, after the Supreme Court upheld lower court decisions and ruled in her favor, Miller said she hoped for an end to the abuse that accompanied each court victory.

"In Britain we are lucky, we are fortunate, to have the ability to voice legitimate concerns and views as part of a shared society. I have therefore been shocked by the levels of personal abuse that I have received from many quarters over the last seven months for simply bringing and asking a legitimate question," Miller said outside court after the ruling, where she was accompanied by bodyguards.
