CMS Cameron McKenna is set to lose a four-partner litigation team in Warsaw led by top-rated Polish dispute resolution head Pawel Pietkiewicz.

The group also comprises litigation partners Michal Subocz, Lukasz Hejmej and Tomasz Manicki.

All four are understood to be joining White & Case, although the US firm was unable to confirm the hires.

Camerons has appointed its Warsaw head of commercial Malgorzata Surdek to lead the local dispute resolution practice following the resignations. Meanwhile, Warsaw employment head Katarzyna Dulewicz will see her duties extended to become head of commercial in the office.

Pietkiewicz is one of Poland's leading litigators and also advises on arbitration matters. He advises on matters including product liability and injury claims and in sectors including pharmaceuticals, cars and tobacco products.

In an internal announcement Camerons' managing partner Duncan Weston said: "Pawel Pietkiewicz, Michal Subocz, Lukasz Hejmej and Tomasz Manicki, partners in our dispute resolution practice in Warsaw, have decided to leave the firm and join White & Case. We wish them every success for the future."

Camerons has 24 partners in Warsaw following the departures. Earlier this year it added a partner in Warsaw with the hire of Irek Piecuch from Polish telecoms operator TPSA.

Other recent lateral moves in the Polish market include DLA Piper's November hire of Hogan Lovells' Warsaw head of intellectual property, media and technology in Warsaw – Krystyna Szczepanowska-Kozlowska – to head up the firm's practice in Poland.
