An Essex Police recruit forced out because of his dyslexia is seeking £500,000 compensation.
But the force said it plans to "vigorously" fight the claim made by Owen Brooking, 24, who was based at South Woodham Ferrers police station.
An employment tribunal in Stratford, London, ruled Mr Brooking was discriminated against by the police.
The tribunal said he had "no option" other than to resign and that certain officers had set out to "intimidate and humiliate" him over his disability.
After the hearing, his solicitor John Mackenzie said: "Mr Brooking is now seeking £500,000 in compensation to reflect lost earnings and pension rights from having a possible 30-year career as a police officer blocked."
Essex Police said they will contest any payout and are considering an appeal.
"Essex Police are in receipt of this judgment and are hugely disappointed by it," a spokeswoman said.
"We are considering with our legal advisers the issues raised and whether there are any grounds to appeal.
"The hearing regarding the amount of compensation to be paid has not taken place and, as a result, we are limited in the comments we can make but Essex Police will dispute vigorously the sum of £500,000 claimed."
A hearing will take place at the tribunal in Stratford on June 17 to decide the level of payout
