Various corporate oppression proceedings
I am frequently briefed in corporate oppression proceedings. These range from relatively straightforward disputes between quasi-partners to complex disputes involving solvent liquidations and difficult issues in relation to the preparation of accounts and valuations. These disputes frequently resolve - either at an early stage, or at or following mediation.
Disputes involving real estate agents
In recent years I have acted for and against many firms of estate agents, including in many disputes between agencies and former salespeople involving allegations of breach of restraint and misuse of confidential information. I have also acted in many disputes involving allegations of misleading or deceptive conduct in the marketing and sale of properties.
