Unpaid rent and eviction

The tenant stopped paying rent and ignored maintenance, which we had to cover ourselves. We have proof, and the court case has been dragging on for a year. All evidence, including the tenant’s written statement agreeing to vacate in June, has been submitted, which I believe now amounts to contempt of law. Yet the civil judge keeps granting more time and delaying hearings without any clear reason. It feels like the system sides with offenders over victims. I’m wondering if I can take this to a higher court or if there are grounds for a police complaint. I have bank statements and proof showing no rent or even basic utility bills have been paid, and the tenant still refuses to vacate. The registered rental agreement states that after two years either party can terminate the lease, and the 90-day clause for non-payment of rent invalidates the agreement.
