The ABA/BNA Lawyer's Manual on Professional Responsibility is reporting that "[l]awyers licensed outside New York are finally allowed to engage in temporary law practice in the Empire State, thanks to a new court rule adopted Dec. 10. With this long-awaited step, New York became the 47th state to adopt a version of ABA Model Rule 5.5 on multijurisdictional practice. The new temporary practice rule goes into effect Dec. 30, or as soon as certain steps required by New York judiciary law are completed. The New York rule differs from the MJP rules of other states in a couple of ways. Most notably, it allows temporary practice not just by lawyers licensed in other U.S. jurisdictions, but also by lawyers who are authorized to practice law in a non-U.S. jurisdiction. Also, New York's new MJP rule is a rule of attorney admission rather than a rule of professional conduct. This approach enabled MJP to be adopted in New York without getting approval from the presiding justices of the four appellate divisions, as is required for professional conduct rules."
