open question

An unresolved issue, one that has not been finally determined. For example, Whether the town should pave all the unpaved roads remains an open question. In the mid-1800s this term acquired a specific meaning in the British Parliament, that is, "an issue on which members may vote independently, without respect to their party affiliation."

open question, an

An issue that has not been finally settled or determined. The adjective open has been so used since the early nineteenth century. The term acquired a specific meaning in the British Parliament: on open questions members may vote as they wish, independent of party. David Masson used it figuratively, as it often is today: “The summary decision of what had hitherto been an open question in the Church” (The Life of John Milton, 1859).
