A multiple sclerosis sufferer has won her appeal to the House of Lords to clarify the law on assisted suicide.
Debbie Purdy, from Bradford, is considering going to Switzerland to end her life, but fears her husband may be charged on his return to the UK.
Wheelchair-bound Ms Purdy, 46, has been seeking an assurance that Omar Puente would not be put on trial.
The maximum penalty for aiding and abetting suicide is 14 years in jail.
She went to the Lords - the highest court in the land - to get the law on assisted suicide clarified.
Five Law Lords unanimously backed her call for a policy statement from the Director of Public Prosecutions (DPP).
This relates to the circumstances in which a person such as her husband might face prosecution for helping a loved one end their life abroad.
In reaction to the Lords' ruling, Ms Purdy said: "It feels like everything else doesn't matter and now I can just be a normal person.
"It's terrific. It gives me my life back. We can live our lives. We don't have to plan my death."
The Lords upheld Ms Purdy's argument that the DPP, Keir Starmer QC, should put in writing the factors that he regarded as relevant in deciding whether or not to prosecute.
Mr Starmer said prosecutors would start work immediately to produce a policy setting out the reasons why prosecutions should or should not be brought in future.
He said an interim policy would be in place by September.
He added: "Once our interim policy is published, we will undertake a public consultation exercise in order to take account of the full range of views on this subject.
"In the continuing absence of any legislative framework by then, I will publish my finalised policy in the spring of 2010."
The Lords' judgement will bring reassurance to thousands of people faced with the same dilemma.
Ms Purdy had taken her case to the House of Lords after the High Court and Court of Appeal ruled it was for Parliament, not the courts, to change the law.
