ALBANY – The Court of Appeals will grapple Tuesday with the issue of whether a reporter can be forced by a Colorado court to disclose the identity of a source when that information would be shielded within the borders of New York.

The case, Holmes v. Winter, 245, involves the attempt by James Holmes to bolster his insanity defense against charges he is the so-called “Batman killer” who shot 12 people to death and injured 70 at a screening of the movie “The Dark Knight Rises” in Aurora, Colo.
