This is the best summary I could come up with:

India’s supreme court has ruled that the government acted lawfully when it revoked the autonomy of the state of Jammu and Kashmir and brought it directly under control of the centre.

Article 370, which for almost 70 years had enshrined special rights for Jammu and Kashmir outside the Indian constitution, was revoked by the government of Narendra Modi in August 2019 through a presidential order, with no consultation with the Kashmiri people.

The abrogation of article 370 was enforced by a lengthy crackdown on the state, where the military was mobilised in huge numbers, political leaders were jailed, a strict curfew was imposed and the internet was shut down for 18 months.

Prior to the judgment, on Monday Kashmir’s political leaders alleged they had been placed under de facto house arrest as the gates of their homes were chained shut, and movement was restricted in the state.

After Jammu and Kashmir became part of the Indian union, article 370 was passed initially as a temporary measure to enshrine certain independent rights and protections for Kashmiris, including their own constitution and flag.

Mehbooba Mufti, the former chief minister who was deposed from power, said revoking article 370 was “unjust, illegal and unconstitutional” and that its justification by the supreme court was “no less than news of a death sentence not only for Jammu and Kashmir but also for the idea of India”.

The original article contains 569 words, the summary contains 231 words. Saved 59%. I'm a bot and I'm open source!

Somewhat unrelated to the news but gave me a chuckle, but the judge ruling in favor of the decision is named Dhananjaya Chandrachud.

The first name translates to "conqueror of wealth" and the first part of the last name is "moon." So he's literally Moon-Chud the conqueror of wealth.

I mean this is the same court that said Modi had no involvement in the Gujarat Massacre so not exactly surprised they don't care about Kashmir either.
