The American Bar Association and the U.S. Department of Education are headed to federal court Wednesday to wrangle over eligibility for the department’s popular Public Service Loan Forgiveness program.

The ABA has asked Judge Timothy Kelly of the U.S. District Court for the District of Columbia to issue a preliminary injunction stating that its employees qualify for loan forgiveness—a claim the department refutes. The department has countered that ABA employees aren’t eligible for the program because the ABA is not primarily a public service organization, even if certain ABA projects perform public service functions.
