"Must Needs Be"

In Kaley v. United States, 134 S. Ct. 1090 (2014), Justice Kagan's opinion for the Court used this interesting phraseology: "The grand jury that is good enough—reliable enough, protective enough—to inflict those other grave consequences through its probable cause findings must needs be adequate to impose this one too." (Emphasis added.) 

At least that's what it said on February 25, 2014, the day it was announced. That sentence was changed soon after the opinion was released. It now says: "The grand jury that is good enough—reliable enough, protective enough—to inflict those other grave consequences through its probable cause findings must be adequate to impose this one too." (Emphasis added.)

You can see the differences below. Google Scholar's version of the opinion still says "must needs be" while the slip opinion on the Court's web site says "must be". In the altered opinion, you can tell that the spacing between letters has been increased so that the sentence still takes up the same amount of space minus the "be".
