The two Tinker documents are final orders from the New Hampshire Supreme Court that decided the merits of Tinker's cases. They are not Supreme Court opinions. The Supreme Court publishes final orders for informational purposes, but, unlike opinions, they have no precedential value and you aren't supposed to cite them in any pleadings or rulings in any court in New Hampshire.
Until recently, final orders were not easily available. They weren't published anywhere - in print or online. You had to request a copy of a final order from the Supreme Court clerk's office. Final orders from September 2014 to the present are now available on the Supreme Court's website. For older orders, you'll still need to contact the clerk's office.
