In plain terms. JAR is the Department of Justice's supplement to the FAR, adding DOJ-specific contract rules.
Who it applies to. Contractors serving the Department of Justice and its components.
What it requires. Meet the FAR baseline, then JAR additions. DOJ work can involve law-enforcement-sensitive and personal information, so expect safeguarding and information-handling terms tied to that data.
Why it matters. Law-enforcement-sensitive data raises the stakes for security and confidentiality on DOJ contracts.
Citation. JAR, the Justice Acquisition Regulation supplement to the Federal Acquisition Regulation (FAR), codified in the FAR System at Title 48 of the C.F.R.
