Whether enforcement of an IRS summons against a taxpayer's attorney violates the taxpayer's Fifth Amendment privilege against compelled self-incrimination.
Holding
No. A summons directed to the attorney does not compel the taxpayer to testify or to produce anything.
Reasoning
The Fifth Amendment protects a person from being compelled to be a witness against himself. Because the summonses required the attorneys, rather than the taxpayers, to produce the documents, the Government imposed no physical or moral compulsion on the taxpayers themselves.
Couch v. United States controlled the basic point. There, the Court held that a taxpayer could not invoke the Fifth Amendment to stop an accountant from producing the taxpayer's records because the essential element of personal compulsion was missing. The taxpayers here were no more personally compelled merely because the documents had been transferred to lawyers rather than accountants.
An attorney's agency relationship with the client does not make the attorney the client for Fifth Amendment purposes. The taxpayer remains free to assert any privilege against being personally forced to testify or personally produce papers; the transfer simply permits the Government to seek the papers from a third party without compelling the taxpayer.
The Fifth Amendment is not a general constitutional right of informational privacy. It protects against compelled self-incriminating testimony, while other doctrines—including the Fourth Amendment and evidentiary privileges—address other forms of privacy interests.
