Nonpartisan

In political science, nonpartisan denotes an election, event, organization or person in which there is no formally declared association with a political party affiliation. The Merrian-Webster dictionary's definition of "nonpartisan" is:

"Not partisan; free from party affiliation, bias, or designation."

Some nonpartisan organizations are truly such; others are nominally nonpartisan but in fact are generally identifiable with a political party.
