A major event for the Minnesota judicial branch of government is on tap Monday — and we're not referring only to the scheduled oral arguments in The Ninetieth Minnesota State Senate et al. vs. Mark B. Dayton, aka the line-item veto lawsuit.

To be sure, that's an important case, positioned to define and potentially limit gubernatorial veto power. It springs from Gov. Dayton's veto in May of the Legislature's entire operating budget in an attempt to convince legislators to reopen negotiations on several contentious provisions in bills he had already signed into law.

What will make Monday's arguments even more noteworthy is that for the first time in court history, they will be livestreamed online at www.mncourts.gov/SupremeCourt. Beginning next month, all oral arguments in cases before the state's highest court will be livestreamed.

Livestreaming is a big step toward greater visibility for the branch of government that for many Minnesotans is the least well understood or appreciated. Minnesotans' ability to witness the court in action in real time on any internet-enabled device ought to demystify its operations. The result should be a greater sense of connection to the courts.

The high court lags the other two branches of state government in livestreaming public proceedings. But it's making the move soon after ending an 11-year partnership with Twin Cities Public Television that included posting video recordings of oral arguments on TPT's website. When that arrangement ended last year, and the State Capitol's elegant but small Supreme Court chamber became available again after renovation, court administrators moved to install the technology needed to livestream oral arguments from that space.

"The Minnesota Supreme Court is committed to maintaining the public's trust in our court," Chief Justice Lorie Gildea said as she announced that livestreaming would begin at 9 a.m. Monday. Opening a wider window on the court at work should do just that, as it provides voters with more opportunity to evaluate the seven justices' performances and hold them to account at the polls. Our bet is that Minnesotans who view Monday's livestream are in for a good show.
