Law firm merger activity picked up after a sluggish first quarter in part due to a renewed increase in transatlantic marriages between large domestic firms and those headquartered in England.

Among the 10 mergers reported last quarter by legal consultancy Hildebrandt Baker Robbins -- one more than during that time frame last year -- was the union of Washington stalwart Hogan & Hartson and London-based Lovells to form Hogan Lovells, which the report characterized as the second-largest since Hildebrandt began tracking quarterly merger activity.

A second cross-border marriage of equals, between Chicago-based Sonnenschein Nath & Rosenthal and London's Denton Wilde Sapte, was announced last quarter but is not included in that figure because the merger will not be completed until later in the year.

Industry analysts say that after a period of caution, U.S. firms are once again looking for markets in which to expand -- and the obvious one for some is London, where many firms specialize in the kind of corporate transaction work that has long been the bread and butter of New York.

The Oregon Supreme Court has ruled that Philip Morris does not have to pay $100 million in punitive damages to the family of a smoker who sued the tobacco giant over its low-tar cigarettes.

The case, however, is going to another jury to decide just how much the death of Michelle Schwarz from lung cancer in 1999 will cost Philip Morris — and legal experts say it could easily be another big award.

A Multnomah County jury in Portland originally awarded the Schwarz family $150 million in March 2002 before the trial judge reduced it to $100 million.

On Thursday, the Oregon Supreme Court vacated the $100 million award and sent the case back to the trial court to reconsider the punitive damages after ruling the judge failed to properly instruct the jury.

The court said the judge should have told the jury it could not punish Philip Morris directly for harm caused to others besides Schwarz.

But the court also supported the trial judge, who had rejected jury instructions the tobacco company had requested.

Peter J. Henning follows issues involving securities law and white-collar crime for DealBook’s White Collar Watch. As Congress works on the final version of the financial regulatory bill, a major change in liability for corporate law firms, accounting firms and investment banks has been inserted into the measure. House members of the conference committee agreed to add a provision offered by Representative Maxine Waters, Democrat of California, to restore aiding and abetting liability for private securities fraud cases.

The impact of the amendment is significant because it expands the potential defendants in securities fraud class actions to include more than just the company accused of making misstatements or omissions, and these are defendants with deep pockets.

BP said Tuesday it has accelerated its process of approving payments for commercial claims related to the Deepwater Horizon oil spill, but two Miami law firms representing fisherman said the oil company’s claim forms are flawed.

BP said it approved initial payments toward 90 percent of commercial large-loss claims that have been filed as a result the ongoing oil disaster. The U.K.-based oil giant said it approved payment of 337 checks for a total of $16 million to businesses that have filed claims in excess of $5,000.

This week, the two firms, Grossman Roth, P.A. and Bilzin Sumberg Baena Price & Axelrod LLP, began representing 600 fishermen from the Florida Keys Commercial Fisherman's Association. They warned that BP’s oil spill claim forms are seriously flawed.

“The claim form that BP put on its website is inadequate under the federal Oil Pollution Act,” said Andy Yaffa of Grossman Roth.

A federal appeals court on Wednesday upheld the city of Redondo Beach's ordinance allowing for the arrest of day laborers who approach automobiles soliciting work.

A divided three-judge panel of the 9th U.S. Circuit Court of Appeals reversed a lower-court decision.

The appeals court said the city's ordinance, modeled after a Phoenix law upheld by the same court, was a reasonable response to traffic problems that officials said day laborers soliciting work caused at two city intersections. The 2-1 majority noted that Redondo Beach allowed the day laborers an alternative forum to seek work such as passing out literature on sidewalks and in parking lots.

Judge Sandra Ikuta wrote for the majority that "we conclude that the Redondo Beach ordinance is narrowly tailored to serve Redondo Beach's significant interests in traffic flow and safety."
