Consider this statement made in your text: [T]he lawyer is often in a position of privilege and power compared with the client, especially the unsophisticated individual client. People may have to use a lawyer for the first time when they are in a vulnerable social, emotional and financial situation and need legal help quickly when they suffer a disputatious [or litigious] relationship breakdown or get arrested and charged for a criminal offence. Indeed, many clients who have not previously engaged a lawyer and had experience with the legal system will be at a disadvantage in bargaining with them [the lawyer] about what services will be provided and at what cost. (Parker & Evans, 3rd ed, 2018: 253-54) In light of these statements, reflect on how legal costs are regulated (as explored in Topic 9 & Chapter 8 of your text, and the material provided by the NSW Law Society). Respond to this key question: Do you agree that the professional conduct rules related to lawyers' costs and billing protect clients and assist clients to guard themselves against excessive legal costs
