Monday is judgment day for Najwa Petersen and the three men she allegedly hired to kill her entertainer husband Taliep.

Shortly after 10am, Cape High Court Judge Siraj Desai is expected to start delivering the findings that he has arrived at in more than a month of deliberation.

The trial began in April, and counsel for the State and defence presented closing arguments over two-and-a-half days in October.

Given the complexity of the case, it is likely that Desai will take more than a day to read out his judgment.

Taliep was shot in the neck in an execution-style killing in the couple's Athlone, Cape Town, home on the night of 16 December, 2006.
