Discrete actions are clearly defiend events that have a definite beginning and, in most cases, a definite conclsusion. See Ornelas v. Department of Justice, EEOC Appeal no. 01995301 (September 26, 2002). Examples include terminations, non-selections, failures to promote, transfer denials, suspensions, leave restrictions, officials reprimands, etc.
The Chateau Marmont in Hollywood has a similar connection to a celebrity death that it will never be able to shake -- and perhaps doesn't want to. In 1982, Saturday Night Live's John Belushi died of a drug overdose there at the age of 33.
For the defense of France of 1814, Marmont continued in his command of the VI Corps. That January he concentrated his troops at Metz and then fell back from Verdun and Saint-Dizier before fighting at Brienne. The next month Marmont fought at La RothiÃ¨re, Champaubert, Vauchamps, Montmirail, Meaux, and Tresmes.
