Docket Use Policy
As of 2020, there is a $1,500 per user cap on docket costs accrued each academic year on Bloomberg Law. Thirty days after you reach this level, your use of the dockets database will be restricted and you will not be able to incur further costs until the next year. Once logged into Bloomberg Law, you may track your docket costs by going to My Account > My Dockets Billing. Please contact Research Services or our Bloomberg Law representative if you have any questions or would like recommendations for minimizing your accrual of costs.
