Warwickshire Police have confirmed they will not appeal against a decision by a council to give the green light to a major motorcycling event.
The force was opposed to Stratford District Council's decision to grant the organisers of the Bulldog Bash 2008 a licence.
The force had formally objected to the organisers' application, saying that they felt the event, held in Long Marston, could compromise public safety.
After seeking legal advice, the force announced it will not appeal against the decision but stressed it will be undertaking "careful planning" to ensure public safety.
In a statement, assistant chief constable Bill Holland said: "Following careful consideration and legal discussions, Warwickshire Police has taken the decision not to appeal against Stratford District Council's decision to grant a premises licence for Bulldog Bash.
"The force objected to a licence being granted because we firmly believe that public safety could be compromised if the event takes place. The granting of this licence is a decision for the licensing authority. It is not a decision made or supported by Warwickshire Police.
"I would stress that our primary objective is to protect people living, working or visiting Warwickshire, including members of all biker groups, from harm. Careful planning with event organisers, the responsible local authority, other forces and public services will now take place."
Hells Angels member Gerry Tobin was shot dead on the M40 in August last year after leaving the long-running motorcycling event.
Police had expressed its concerns to the council but a committee in Stratford-upon-Avon granted it a licence on May 15.
Organisers were granted an annual licence for the event to cover this year's planned August festival and up until 2018.
