Definition of "unopposed"

A number of other mergers of U.S. railroads are mooted, but the I.C.C. [Interstate Commerce Commission] has made it clear that its assent to the N.& W.-Virginian proposal, which was unopposed by competitors or stockholders, should not be taken as an indication that others will swiftly pass its scrutiny.
