From the bdafrica story, its quite clear that KRA was stopped from collecting the said claims,which offcourse doesn't affect .

KRA has been making blanket claims from many firms then tries to 'blackmail' them into a settlement.

KRA vs Keroche - Keroche won. I am not sure if KRA tried to get the judgment overturned by appealing.

KRA vs Bidco - Bidco went to court for relief. I think it is still being litigated.

There are many cases which go unhighlighted. The goal of KRA employees is to threaten 'closure' as well as freezing bank accounts so that the firm suffers irreparable damage unless they cough up money.

Some e.g. Keroche and Bidco decide to fight it out. Some with fewer resources and connections just settle.

Kenya Re needs to battle this out.

and now kings way want a refund of more than 2b they were blackmailed to pay back in 2002 (business daily)

Kingsway is being told to pay KES 2.4bn or have their assets seized. That's a reason not to have just one bank account or a single source of income or assets. I am not sure what Kenya Re can do but appeal. It would be silly of KRA to freeze KenRe's account which would devastate its business which relies on making timely re-insurance premiums and payments to its fellow re-insurers and clients.

Good move which will lead to more revenue hence a rise in the share price
