(1913)

1. An injunction granted to prevent an action that has been threatened but has not yet violated the plaintiff’s rights.

quia timet:
[Latin “because he fears”]
(17c)

1. A legal doctrine that allows a person to seek equitable relief from future probable harm to a specific right or interest. [1]

     Excerpt from Charles Herman Kinnane’s A First Book on Anglo-American Law (2d ed. 1952):

     “A second class of cases where equity courts act to prevent injury are known as ‘quia timet’ cases. The name comes from the two Latin words, once used when asking relief in this class of cases; the words mean, ‘whereas he fears’ that some injury will be inflicted in the future unless the court of equity assists him in advance, the plaintiff asks the assistance of the court to do this, that, or the other thing with respect to the defendant.” [2]
