Forum Selection Clauses. Do NOT Try These At Home
2009-08-10 15:45:00 I just got an email from a small tech company in China asking me whether its contract should call for Chinese or Russian law. My response was pretty much that I had no idea because it would depend on what was in the contract and what was most important. There is no way to know what law someone should prefer unless you first know what really matters. In my response, I also told them that the choice of forum could be as or even more important. My tiny law firm ("boutique" when I am trying to sound highfalutin) has made well over $100,000 the last couple of years fighting over badly written forum selection clauses in international contracts. Our clients (who consulted us for the first time only after they had signed these agreements and right before they were ready to sue on them) could easily have avoided the entire expense had they only done things right with their forum selection clauses in the first place. Here are the cases: 1. One had a provision calling for arbitration...

Such benefits include:--- The ease of implementing the solution-- The satisfaction they feel when they have the solution.-- How easy and inexpensive your solution is compared to the merchant trying to solve his problem alone.-- How safety, Confidence and satisfaction are ...

Faith schools accused of 'backdoor selection'
2009-03-03 07:24:00 Alexandra Frean, Education Editor, The Times, writes,'Faith schools and academies should be stripped of their power to choose pupils, according to research that suggests that some secondary schools are flouting new rules designed to prevent middle-class pupils dominating the best comprehensives.Researchers at the London School of Economics, who studied more than 3,000 secondary school admission forms for 2008, said that faith schools and other establishments that control admissions, including academies, should hand over the job of allocating places to an independent body to ensure greater fairness. Anne West, director of the education research group at the LSE and lead author of the study, said that this could be the local authority, which already controls admissions for community schools, or a religious body such as the diocesan authority.The researchers found that some schools were operating a form of backdoor selection by asking for personal information about parents? marital st...
