Affirming partial victory for a litigant who defended her own student loan collection case, a state appeals court has ruled that the New Jersey Higher Education Student Assistance Authority is entitled to recover principal and fees, but not interest, because it failed to provide documentation of the borrowing rate originally agreed upon.

The Appellate Division on Tuesday affirmed a trial judgment of $7,576, less than the authority claimed it was owed in the case—in which it relied on print-outs generated right before trial as documentary evidence of the loans’ interest rate.
