Join the Los Angeles Times for an interactive live Web chat with a constitutional expert on Tuesday’s Supreme Court hearing on Proposition 8.

The Times will be joined from Washington by David Gans, civil rights director of the Constitutional Accountability Project. Readers can submit questions live.

The Times’ David G. Savage and Noam N. Levey wrote earlier Tuesday that the Supreme Court justices sounded closely split on gay marriage Tuesday, but Justice Anthony M. Kennedy suggested the court should strike down California’s ban on same-sex marriage without ruling broadly on the issue.
