Confidentiality
Rules limiting access to or distribution of certain information.
Confidentiality involves a set of rules or a promise, sometimes executed through confidentiality agreements, that limits access to or places restrictions on the distribution of certain types of information. It is a key concept in legal, medical, and other professional contexts, with specific duties and exceptions varying by jurisdiction.
- Legal confidentiality
- Lawyers are often required to keep confidential anything on the representation of a client; the duty is broader than the attorney–client evidentiary privilege.
- Medical confidentiality
- Conversations between doctors and patients are protected by physician-patient privilege, dating back to the Hippocratic Oath.
- Breach of confidence requirements
- Three elements: information must have quality of confidence, imparted in circumstances importing obligation of confidence, and unauthorized use to detriment of the party.
- UK curtailment
- Recent legislation curtails confidentiality professionals like lawyers and accountants can maintain at the expense of the state.
- HIV confidentiality in UK
- Information about HIV status is kept confidential within the NHS, based in law, the NHS Constitution, and key NHS rules.
Lore & Background
Confidentiality in law requires lawyers to keep client information confidential, encouraging clients to speak frankly. Exceptions exist in most jurisdictions when the lawyer believes the client may kill or seriously injure someone, cause substantial financial injury, or use the lawyer's services to perpetrate a crime or fraud. In such situations, the lawyer has discretion to disclose, but a few jurisdictions make this mandatory.
Reader's Guide
Confidentiality serves as a foundational principle in both legal and medical fields, promoting trust and open communication. In law, it enables zealous representation by encouraging clients to share all relevant facts, even those that might seem incriminating. In medicine, it protects patient privacy under laws like HIPAA and the Hippocratic Oath, though exceptions exist for reporting gunshot wounds or impaired drivers. The balance between confidentiality and public safety remains contested, with jurisdictions varying on mandatory versus discretionary disclosure. The concept also extends to professional contexts like accounting, where UK law now requires disclosure of fraudulent accounting. Overall, confidentiality is a dynamic legal and ethical concept, shaped by statutory rules, professional codes, and court decisions.
Did You Know?
- The duty of confidentiality for lawyers is broader than the attorney–client evidentiary privilege, which only covers communications between attorney and client.
- In the UK, accountants are required to disclose to the state any suspicions of fraudulent accounting and even legitimate use of tax saving schemes not already known to tax authorities.
Frequently Asked Questions
What is Confidentiality in legal terms?
Confidentiality is a set of rules or a binding promise that restricts who may access certain information and how it can be shared. It operates through confidentiality agreements and professional duties in legal, medical, and other specialized fields, with the exact scope and exceptions shifting depending on the jurisdiction.
What must a plaintiff prove to win a breach-of-confidence claim?
Three elements are required: the information must possess a quality of confidence, it must have been shared under circumstances that create an obligation of confidence, and the defendant must have used or disclosed it without authorization to the detriment of the person who shared it.
Where does medical confidentiality come from?
The protection of doctor–patient conversations traces back to the Hippocratic Oath and is now codified in the physician-patient privilege recognized in many jurisdictions. It ensures that patients can speak openly with their providers without fear that their disclosures will surface in legal proceedings.
Why is Confidentiality considered a foundational legal concept?
It underpins trust in every professional relationship where sensitive information flows—lawyers, doctors, therapists, and corporate officers all rely on it to function. Without a predictable rule limiting disclosure, clients and patients would withhold the very information those professionals need to help them, collapsing the system.
