While there may, at a highly technical level, be some subtle and important differences between "justiciability" and "jurisdiction," it seems to me that the two are often used synomously in practice. The law school cite I posted earlier, for example, addresses the limits on "jurisdiction" imposed by the "cases and controversies" language of article 3. What follows purports to be an excerpt from "The Oxford Companion to the Supreme Court of the United States."
"Justiciability: Article III, section 2 of the Constitution defines the categories of federal jurisdiction in terms of cases and controversies. This has led the Supreme Court to hold that federal courts may take jurisdiction only of “justiciable” disputes, that is, those “appropriate for judicial determination” (Aetna Life Insurance Co. v. Haworth, 1937, p. 240). In Aetna, Chief Justice Charles Evans Hughes distinguished justiciable controversies from those merely hypothetical or moot. He stressed that there must be “a real and substantial controversy admitting of specific relief through a decree of a conclusive character” (p. 241). Justiciability is a conceptual umbrella covering several related doctrines or problems, including standing, mootness, and ripeness. It prohibited federal courts from rendering advisory opinions and, until the 1934 Declaratory Judgment Act (upheld in Aetna), declaratory judgments as well. It excludes collusive suits and political questions from federal jurisdiction."

Notice how "justiciability" is defined in terms of "jurisdiction." It also identifies "collusive suits" as being excluded from "federal jurisdiction." In common useage, there seems to be little distinction between the two concepts. This particular explanation says: "This has led the Supreme Court to hold that federal courts may take jurisdiction only of “justiciable” disputes..." If you cannot "take jurisdiction" over a "non-justiciable" dispute, that seems to be a limit on "jurisdiction," don't it?
