Key Facts
- Federal level: Federal law defines ADR as a process using a neutral third party, and it lists mediation as one example.Federal level: Federal and state: Federal level: Each U.S. district court must authorize ADR in civil actions through local rule and must operate its own ADR program.Federal level: Federal law requires litigants to consider ADR at an appropriate stage and requires each district to provide at least one ADR process including mediation.Federal level: Federal courts provide confidentiality protections for confidential ADR communications under 28 U.S.C. § 652 until later chapter 131 confidentiality rules are adopted.National overview: State mediation rules are not uniform, so California’s mediation confidentiality framework under Evid. Code § 1119 should not be treated as nationwide law.State level: California law encourages mediation and describes how mediation can offer greatest benefits when used early before substantial discovery costs.National overview: Both federal procedure and California policy language tie dispute resolution to fairness, timeliness, and cost-effective outcomes, which helps explain why mediation is often discussed as a path to access to justice.
- Federal level: Federal ADR programs must also include neutral selection and training requirements for neutrals used in ADR processes.
- Federal level: Federal civil procedure emphasizes just, speedy, and inexpensive determinations and describes settlement as a purpose of pretrial conferences.
- State level: California’s mediation privilege bars mediation communications and related evidence or writings from admissibility and discovery.State level: California mediation confidentiality applies to communications and certain writings and communications remain confidential.
- Federal level: Federal courts may exempt some cases or categories from ADR consideration and must consult the bar, including the U.S. Attorney, when defining those exemptions.
- Federal level: Federal ADR includes more than mediation, so “ADR” and “mediation” are not interchangeable terms under the ADR Act.
Why mediation shows up in the court system
Mediation is commonly described as a way to improve access to justice because it aims at resolving disputes through a structured process rather than a full adjudication. Federal law and court procedure rules treat dispute resolution efficiency and settlement facilitation as part of how civil cases move, and states often support mediation through their own legislation. This article focuses on what federal law requires for court-connected ADR and how those requirements differ from state mediation rules, using California as a verified example.

Mediation is part of a bigger federal ADR framework, not a separate universe
Federal law defines “alternative dispute resolution” as any process in which “a neutral third party participates to assist in the resolution of issues in controversy,” and it explicitly lists mediation along with other processes. The definition appears in 28 U.S.C. § 651. Because the statute lists multiple dispute-resolution formats (including early neutral evaluation, minitrial, and arbitration), “ADR” operates as an umbrella concept, while “mediation” is one specific ADR process.
Federal law requires each district to build ADR into civil case handling
The federal ADR Act does not leave ADR as an optional add-on that varies by district whim. Instead, it requires each U.S. district court to authorize the use of ADR processes in all civil actions through local rule and to devise and implement its own ADR program through local rule.
Federal law then adds two key, practical requirements: district courts must require litigants to consider ADR at an appropriate stage, and district courts must provide at least one ADR process, including mediation. These requirements appear in 28 U.S.C. § 652.
Exemptions and timing ADR is required to be considered, not blindly mandated
Federal law recognizes that ADR will not always fit every case. Under 28 U.S.C. § 652, a district court may exempt “specific cases or categories” where using ADR would not be appropriate. The same provision states that, in defining exemptions, the district court must consult members of the bar, including the United States Attorney for that district.
This structure is a common point of confusion: federal law requires litigants to consider ADR and requires districts to offer at least one mediation-inclusive ADR option, but it does not automatically eliminate judicial discretion to treat ADR as inappropriate in limited categories.
Federal ADR confidentiality protected communications until later chapter rules
Confidentiality is often the reason mediation is viewed as a workable forum for candid negotiation. For federal court ADR, 28 U.S.C. § 652 contains a confidentiality instruction that applies “until such time as rules are adopted under chapter 131” for confidentiality of ADR communications.
At that level, the statute directs district courts to provide for confidentiality and to prohibit disclosure of confidential ADR communications by local rule. The statute’s framing is jurisdiction-specific: it sets a federal-court confidentiality approach for confidential ADR communications, but it does not automatically override state evidence or privilege law in state proceedings.
Neutrals and selection federal ADR programs must handle who serves
Mediation in federal ADR is also shaped by rules about neutrals. Under 28 U.S.C. § 653, a district court that authorizes ADR must adopt processes for making neutrals available for each ADR category offered and must promulgate its own procedures and criteria for selecting neutrals.
The statute also includes a qualifications concept, stating that neutrals “should be qualified and trained” to serve in the appropriate ADR process. It identifies examples the district court may use, including trained magistrate judges and professional neutrals from the private sector. This requirement matters because it helps explain why federal mediation is not just informal settlement talk; federal law expects neutrals to be selected and prepared under a formal process.
How federal civil procedure supports settlement and efficiency
The federal ADR Act fits into a broader federal civil procedure theme: courts and parties manage litigation to avoid unnecessary delay and expense. The Federal Rules of Civil Procedure instruct that the rules should be construed and employed to secure the “just, speedy, and inexpensive determination of every action and proceeding.” The committee print containing Rule 1 and Rule 16 states this in the rule text. See the Federal Rules of Civil Procedure Rule 1 and Rule 16.
Rule 16 also lists purposes for pretrial conferences, including “facilitating settlement.” It further allows a court, at any pretrial conference, to consider “settling the case and using special procedures to assist in resolving the dispute when authorized by statute or local rule.” Those provisions help tie federal ADR and mediation to official procedure goals rather than treating mediation as a side activity.
California as a state example mediation encouragement and a mediation privilege
State mediation rules vary, so California is best treated as a concrete example rather than a stand-in for all states. California’s mediation statute includes legislative findings that the “peaceful resolution of disputes” in a fair, timely, appropriate, and cost-effective manner is an essential function of the judicial branch. It also states that “Many disputes can be resolved” through less formal processes such as mediation and that mediation is encouraged and used where appropriate. The legislative findings appear in California Code of Civil Procedure § 1775.
California also identifies a timing theme: mediation “can have the greatest benefit” when used early, before substantial discovery and other litigation costs. The statute further includes specific estimates for court processing costs and a success savings threshold tied to court and party savings, including an average cost figure of $3,943 and an estimated savings threshold of at least $250,000.
For confidentiality, California has a mediation privilege rule. California Evidence Code § 1119 provides that evidence or admissions made for the purpose of, in the course of, or pursuant to mediation (or a mediation consultation) are not admissible or subject to discovery, and it states that mediation communications remain confidential. It also bars disclosure of certain writings prepared for mediation or a mediation consultation.
Federal vs. California mediation confidentiality a compact comparison
Federal and state systems handle mediation confidentiality differently because they rely on different controlling texts. The table below summarizes what each cited statute requires at a high level.
| Confidentiality point | Federal court ADR under 28 U.S.C. § 652 | California mediation under Evid. Code § 1119 |
|---|---|---|
| Baseline rule in the statute | District courts must provide confidentiality and prohibit disclosure of confidential ADR communications by local rule, applying until later chapter-131 rules are adopted. | Mediation communications and certain mediation-related evidence/admissions/writings are not admissible and are not subject to discovery, and communications remain confidential. |
| Controlling text | 28 U.S.C. § 652 | California Evidence Code § 1119 |
These differences help explain why mediation confidentiality can feel unpredictable across jurisdictions: the confidentiality regime comes from the legal forum’s controlling statute and privilege rules, not from one nationwide mediation rule.
Common mix ups when people read about mediation in “federal” and “state” contexts
People often blend concepts in three ways.
- ADR vs. mediation: the federal ADR Act uses “alternative dispute resolution” as a broader label that includes multiple processes, so “ADR” and “mediation” do not mean the same thing under 28 U.S.C. § 651.
- Federal court requirements vs. state court practices: federal mediation rules in civil cases depend on district court local rules and federal statutory instructions, while state mediation privilege and procedure rules depend on state law.
- Confidentiality rules coming from different sources: federal confidentiality is directed by 28 U.S.C. § 652 until later chapter rules are adopted, while California confidentiality and admissibility/discovery protections come from California Evidence Code § 1119.
