English to Portuguese Law/Patents Law (general) Power of Attorney

Prezados Colegas,

Gostaria de saber a melhor tradução para EITHER IN OR OF JUDICATURE no seguinte contexto:

To discharge all the functions of board and administrations of all the business of the corporation and of all that may pertain thereto, including all its assets and properties, whether real or personal, with such general and special authority as to principal and supplementary matters as may be necessary, being empowered to collect, EITHER IN OR OF JUDICATURE, and receive all kinds of products, prices, instalments, rents, dividends, income and profits and such other amounts, fruits, effects securities, credits, indebtedness and emoluments.

Pelo sentido parece ser POR VIA JUDICIAL OU EXTRAJUDICIAL, vocês confirmam ou sugerem outra tradução mais adequada?

Desde já agradeço-lhes a valiosíssima ajuda!!
