Create your own PACER account (you don't need to be a lawyer). Give them your credit card info if you want instant access.
Then when you log in go to the New York - Southern site from the page that lists all the courts, click on the link that says Query and type in 1:15-cv-05916 as the case number and submit it. Pay attention to "Date of Last Filing" (which currently says 8/31). This query is free.
When/if "Date of Last Filing" changes to 9/1, click on "Reports" in the top navbar, then "Written Opinion Report", and again type in the case number and run the report. That report is also free, as will be the opinion whenever it shows up.
But pretty much everything else you do on PACER costs a minimum of $0.10 (even searches with zero results). Though if you spend less than $15 in a quarter the entire amount is waived.
