Are the commas needed?

I couldn't say that they are needed--it's really a matter of style, and in recent decades, there has been a movement to use fewer commas. I would say, though, that they are traditional. Lawyer is the subject of the sentence, and Ronald Ng is placed between the subject and the verb, clarifying who Jing's lawyer is.

(By the way, these symbols: ( and )--are called parentheses in American usage. The singular is parenthesis. These symbols: [ and ]--are called brackets. Perhaps Centrox could comment on the terminology used in England.)

"Brackets" is the general term for this family of symbols, and particular ones are qualified by a preceding word such as round, square, curly, angle, etc. We are aware that Americans may use this term specifically for square brackets.

Round Brackets () are also called parentheses, especially in American English.

Square Brackets [] are also called brackets, especially in American English.

Curly brackets {} are also called braces, especially in American English.

I would add that where it matters, careful British writers use the same terminology as Americans - I mean people involved in preparing material for printing, mathematicians, computer programmers (these symbols are used in many computer languages and have an exact meaning).

Ordinary people tend to call parentheses just "brackets", and when (say) dictating text, might say "open brackets" and later "close brackets". Square brackets are a bit specialised in ordinary text.

Thanks, Setanta and centrox.
