The phrase "get off technicality" means avoiding punishment or liability based on some technicality or minor detail. There are many synonyms for this phrase, such as loophole, evasion, escape, avoidance, and circumvention. These words all describe a situation where someone is able to escape responsibility because of a technicality, rather than because they are innocent or justified in their actions. While technically legal, these actions can often be seen as unethical or unfair, and can lead to frustration and resentment among those who feel that justice has not been served. Ultimately, it is important to consider both the letter and the spirit of the law when assessing these kinds of situations.
