Most-quoted passages
The sentences later courts lift from this opinion, ranked by how many decisions quote each — the parts of the opinion doing the work. These counts are smaller than the citation total above because most of the 344 citing decisions cite the case generally; a passage count includes only decisions quoting that exact language verbatim.
““If this [interception of telephone conversations between the defendant and her counsel] occurred, it was a violation of the appellant’s constitu tional rights. The Fifth Amendment enjoins that no person be deprived of life, liberty or property without due process of law. Such due process includes the right of one accused of crime to have the effective and substantial aid of counsel. Neu-field v. United States, 1941, 73 App. D.C. 174 , 182, 118 F.2d 375 , 383. Moreover, the Sixth Amendment provides that ‘In all criminal prosecutions, the accused shall enjoy the right * * * to have the Assistance of Counsel for his defence.’ “It is well established that an accused does not enjoy the effective aid of counsel if he is denied the right of private consultation with him.””

4 later decisions quote this exact passage · from the majority““We consider it equally true that a defendant and his lawyer have a right to talk together by telephone without their conversations being monitored by the prosecution through a secret mechanical device which they do not know is being used. It would not be an answer to say that the accused cannot complain of the interception of his telephone conversations with his counsel if he had on other occasions ample personal consultation with his lawyer, face to face, which no person overheard. That fact would not erase the blot of unconstitutionality from the act of intercepting other consultations. [Emphasis supplied.]”
