To put an end to the question “will the judge block the merger” here is what the law says:
“Federal law requires a judge to sign off on antitrust approvals, but it is often a formality. Deals typically close before this sign-off, given prior approval from the Department of Justice. While Mr. Leon can't block CVS' takeover of Aetna, he can question whether the Justice Department's review should have been broader, according to the report.”
End of discussion.
Think about it, would the SEC allow Aetna shares to be canceled if there was even a minute chance of the merger being blocked bu a judge once it’s cleared by the DOJ? How would you undo that?
How about the people who bought the billions in bonds? Would they have bought if they was the slightest chance merger would be blocked? Once again what do you do with the bonds?
The SEC knows the law, once DOJ approves the judge is bond by federal law to approve the deal. He can change the conditions but cannot block. Know what the law says before you make a comment.
