Adri Anton Kalangie v Public Prosecutor: Sentencing for Drug Importation and Prospective Overruling

Adri Anton Kalangie appealed his sentence for importing not less than 249.99g of methamphetamine. The Court of Appeal, comprising Sundaresh Menon CJ, Andrew Phang Boon Leong JA, and Judith Prakash JA, dismissed the appeal. The court clarified the doctrine of prospective overruling, holding that the sentencing framework extrapolated from Suventher Shanmugam v Public Prosecutor was correctly applied and the sentence was not manifestly excessive. The court considered arguments regarding the applicability of pre-Suventher sentencing benchmarks and mitigating factors, ultimately finding no grounds for appellate intervention.
