WASHINGTON (7News) \u2014 Luigi Mangione<\/a>\u2019s guilty plea to federal charges could create a significant legal challenge for the separate New York murder case against him, a former federal prosecutor told 7News.<\/p>\n

Mangione, a Maryland man accused of fatally shooting the CEO of a health insurance company, pleaded guilty to two federal stalking charges<\/a> Friday.<\/p>\n

Former federal prosecutor Neama Rahmani discussed what could happen next during an interview with 7News anchor Megan Clarke, saying Mangione\u2019s attorneys are expected to argue that New York\u2019s double jeopardy protections prevent the state murder prosecution from moving forward.<\/p>\n

Parallel federal and state prosecutions generally do not violate the U.S. Constitution\u2019s Double Jeopardy Clause because the federal government and states are considered separate sovereigns.<\/p>\n

Rahmani said New York, however, has additional protections governing successive prosecutions arising from the same conduct. He expects Mangione\u2019s defense attorneys to argue that the federal stalking prosecution and state murder case stem from the same transaction or occurrence.<\/p>\n

\u201cIf so, today’s guilty plea in federal court may completely undermine and torpedo the state murder case,\u201d Rahmani told 7News.<\/p>\n

Whether that argument succeeds will ultimately be decided in court.<\/p>\n

Rahmani pointed to the prosecution of former Trump campaign chairman Paul Manafort as an example of New York\u2019s broader double jeopardy<\/a> protections. State charges against Manafort were dismissed after his federal prosecution.<\/p>\n

Asked whether Mangione could ultimately avoid a state murder trial, Rahmani said it is possible if his attorneys persuade the judge that the federal and state cases arise from the same transaction or occurrence.<\/p>\n

Rahmani questions federal prosecution<\/p>\n

Rahmani also questioned federal prosecutors\u2019 handling of the Mangione case.<\/p>\n

He said prosecutors initially pursued federal charges in part to seek the death penalty, which is unavailable under New York state law. According to Rahmani, the federal death penalty effort failed, while federal murder and firearms charges were also dismissed, leaving two stalking counts.<\/p>\n

Mangione pleaded guilty to those remaining counts without a plea agreement, Rahmani said.<\/p>\n

The former prosecutor argued that federal authorities might have been better served by allowing the state murder prosecution to proceed first.<\/p>\n

\u201cWhat the feds should have done is dismiss their case, let the state go first,\u201d Rahmani said.<\/p>\n

Rahmani said the federal conviction could now provide Mangione\u2019s attorneys with an argument for seeking dismissal of the state charges.<\/p>\n

Double jeopardy fight expected<\/p>\n

Mangione\u2019s New York trial is currently scheduled for Sept. 8, according to Rahmani, although he predicted that date could be postponed as attorneys litigate the double jeopardy issue.<\/p>\n

Rahmani expects the defense to file a motion seeking dismissal of the state case, followed by opposition from the Manhattan district attorney\u2019s office and potentially oral arguments before the judge.<\/p>\n

The legal dispute could also extend beyond the trial court.<\/p>\n

Rahmani said that even if the judge rejects Mangione\u2019s attempt to dismiss the state prosecution, the double jeopardy question could later become an issue on appeal.<\/p>\n

The guilty plea does not itself dismiss or resolve the New York murder case. Any effort to block that prosecution would require further litigation and a court ruling.<\/p>\n","protected":false},"excerpt":{"rendered":"WASHINGTON (7News) \u2014 Luigi Mangione\u2019s guilty plea to federal charges could create a significant legal challenge for the…\n","protected":false},"author":2,"featured_media":321485,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[6],"tags":[9,11,10],"class_list":["post-321500","post","type-post","status-publish","format-standard","has-post-thumbnail","category-new-york","tag-new-york","tag-new-york-headlines","tag-new-york-news"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/us-ny\/wp-json\/wp\/v2\/posts\/321500","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/us-ny\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/us-ny\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ny\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ny\/wp-json\/wp\/v2\/comments?post=321500"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/us-ny\/wp-json\/wp\/v2\/posts\/321500\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ny\/wp-json\/wp\/v2\/media\/321485"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/us-ny\/wp-json\/wp\/v2\/media?parent=321500"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ny\/wp-json\/wp\/v2\/categories?post=321500"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ny\/wp-json\/wp\/v2\/tags?post=321500"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
