I assume this was at a magistrates court?
One of the first stages in a case is `plea before venue' proceedings. The idea is that if the defendant pleads guilty, the magistrates can pass sentence or if they do not have the sentencing power required (for more serious cases) they can send the accused to the crown court for sentencing. The idea is to cut the cost to the taxpayer of having to set up a crown court case only for the defendent to get there and plead guilty.
By declining to enter a plea at this stage the defendent forces the system to go to the crown court for trial by jury. I assume the police in this case are expecting the defendent to enter a not guilty plea hence the comment about dragging on. It may be of course that the defence are keeping their options open.
