Indeed, even communications into the state present risks under the Court's analysis. But even this doesn't help much, seeking to save a client's right to counsel of its choice only be devaluing the advice obtained. Many professionals must address legal concerns in order to give intelligent counsel. Thus, accountants give legal advice. Realtors give legal advice.
Insurance agents give legal advice.
As the dissent notes, even Ann Landers gives legal advice. If the California rule is adopted by other states, the growing national and international business structure will be hobbled by the Balkanized practice of law, increasing legal costs while diminishing client-focused expertise. Absent a national bar, there is a better way. To practice law in a jurisdiction should mean to appear in its courts or to be systematically present physically in the jurisdiction for the handling of repeated transactions for one or more clients. To the extent that local law is applicable, it should be sufficient to retain the expertise of local counsel.
