New York Gov. Kathy Hochul is supporting the city’s effort to suspend a unique legal agreement that requires it to provide emergency housing to homeless people, as a large influx of migrants overwhelms the city’s shelter system.

Hochul endorsed the New York City’s challenge to the requirement in a court filing this week, telling reporters Thursday that the mandate was never meant to apply to an international humanitarian crisis.

The city has for months sought to roll back the so-called right to shelter rule following the arrival of more than 120,000 migrants since last year. Many of the migrants have arrived without housing or jobs, forcing the city to erect emergency shelters and provide various government services, with an estimated cost of $12 billion over the next few years.
