Xia tried another four times to climb Everest — his last attempt in 2016 ended just 200m from the summit because of bad weather.
His dream of scaling the mountain appeared to have ended when the Nepalese Government imposed the rules on double amputees, which Xia described as "discriminating against the disabled".
However, he is now looking forward to his most challenging attempt to scale Everest.
I have to realise it. It also represents a personal challenge, a challenge of fate.
"Climbing Mount Everest is my dream," he told Agence France-Presse.
"I have to realise it. It also represents a personal challenge, a challenge of fate," Xia said.
The decision by Nepal's top court to overturn the ban is also a boost to former Gurkha Hari Budha Magar, 38, who lost his legs in Afghanistan in 2010.
Magar, who was born in Nepal but lives in Kent, had been training for 18 months with an experienced mountaineering team when the ban was announced, causing him to call off his attempt to scale Everest.
The former corporal lost his legs above the knee after he was hit by an improvised explosive device.
