Thousands of women who were victims of the PIP breast implant scandal should receive compensation, a French appeal court has decided.
Women involved in the case say they are elated and exhausted after 10 years of fighting for justice.
The court also upheld an earlier judgement finding German safety body TUV Rheinland negligent.
TUV said it had acted "diligently", and that women must prove they had a PIP implant to be entitled to compensation.
It awarded safety certificates for faulty breast implants made by French company Poly Implant Prothèse (PIP).
The court decision could have far-reaching implications for thousands of other victims around the world.

Jan Spivey, one of 540 British women involved in the case, was given PIP implants after she had a mastectomy due to breast cancer.
After hearing the decision, she said she was "elated and exhausted".
"It's been a very long journey," she said.
"We've been in and out of court, and that's been really difficult for women. We've got health issues and we've got lots of other responsibilities too - PIP has had an impact on the whole of our lives.
"It's been an inescapable issue."
Jan developed aching joints, pain and fatigue after having the implants, and once they were removed it was clear they had been leaking silicone into her body.
