Sunanda Pushkar was discovered dead in the set-up of a five-star lodging in Delhi on 17 January 2014.
Her demise was at first treated as self destruction yet police in Delhi later said she had been killed.
In 2018, they accused Mr Tharoor of abetment to self destruction and remorselessness to his mate – a charge he denied.
A court in Delhi has now excused him of all charges refering to absence of proof.
Mr Tharoor, who went to the court procedures for all intents and purposes on Wednesday, expressed gratitude toward the court for its decision.
“It had been seven and half years and it was a torment. I’m so appreciative,” he said, as per Live Law site.
Shashi Tharoor’s extremely open misfortune
In an explanation posted on Twitter, Mr Tharoor added that the decision brought a “huge end to the long bad dream” which had wrapped him after his better half’s passing. “I have endured many unwarranted allegations and media denunciation quietly, supported by my confidence in the Indian legal executive, which today stands vindicated,” he said.
Mr Tharoor is a MP from the southern province of Kerala for India’s primary resistance Congress party. A negotiator with 25 years of involvement, he filled in as undersecretary general at the United Nations for correspondences and public data.
He wedded Pushkar, a previous Dubai-based finance manager, in 2010.
The reason for Ms Pushkar’s passing is as yet muddled.
The principal posthumous report recommended she might have passed on of a medication glut, however ensuing reports have alluded to “harming”, “strange infusion marks” and, in one case, a “profound chomp” on her palm.
