A Note to Our Readers

We’ve amended what had been a brief blog of the Supreme Court decision in Walsh v. Cardiac Specialists (posted April 13). Our practice is not to change blogs after we post them (except if we spot a typo) so that people won’t think we hide our mistakes. If we ever make one, it will remain on display. But we received an inquiry about an issue we hadn’t mentioned which, on reflection, is at least as important as anything else in the blog. So, while not changing what we originally posted we have added some paragraphs, marking the new section as such.
