Chief Justice Antonio Lamer, who emphasized at the outset that his decision would not deal with the ethical controversies surrounding what Latimer claimed to have been a mercy killing. Latimer also claimed his detention was arbitrary and therefore breached section 9 of the Charter. The Court decided the detention was not arbitrary, as it was carried out because it seemed likely that Latimer was guilty. These were valid grounds for an arrest; the detention fit the definition of a proper arrest even though the police never called it one. The description of the incident as a detention, the police making it clear that he was in their custody by walking him into the house so he could put on different clothes, and Latimer's acceptance that the police were in control were enough for Latimer to understand he was being arrested. The Court then turned to whether the police's decision not to tell Mr. Latimer he was being arrested and could face a murder charge breached section 10(a) of the Charter. This section states one must be "informed promptly of the reasons" for detention or arrest. The Court found section 10(a) was not infringed. Section 10(a) is meant to ensure those arrested or detained are aware of the gravity of the situation. Latimer argued that since the police did not call the detention an arrest, he was not fully aware of how serious the trouble he was in was. He also claimed this was the reason why he had declined to talk to a lawyer. Again, the Court argued the words used did not matter, but rather how the suspect can interpret the situation. Latimer could be expected to understand the seriousness of the situation since he was told he was being detained in connection with Tracy's death. The police had explicitly said the situation was serious, and had told him of rights one has when being arrested. Finally, the case involved section 10(b), the right "to retain and instruct counsel without delay and to be informed of that right". The Court noted it had found in R v Bartle that rights to be informed that one may seek counsel included rights to be told of duty counsel and how to obtain it; i.e., through a free telephone call. Although Latimer was told that legal aid existed, he was not told that he could make a free telephone call and obtain
