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 7 citing decisions cite the case generally; a passage count includes only decisions quoting that exact language verbatim.
“The Commission, as an administrative agency, is peculiarly fitted to interpret its own orders, especially where the question raised concerns the extent and limit of transportation rights granted a carrier under a certificate issued by the Commission.
