Re: Max Fine
There is a maximum fine under the now defunct Data Protection Act, there is no maximum fine under GDPR. There is an upper limit which is determined by a percentage of the company's turnover, and the fine, in pounds sterling, can be anywhere from 0 to that upper limit, but the higher the company turnover, the higher the upper limit There is no limit to the upper limit.
In Facebook's case the fine they would pay under GDPR would be anywhere from zero to $1.6 billion.
A company with a higher turnover, the upper limit on the fine would be higher.
