¶1 Where two offenses are the same in law and fact and there is no indication that the legislature intended to allow convictions for both offenses, it is a violation of double jeopardy to convict a defendant of both *4offenses.1 Here, Miguel Angel Villanueva-Gonzalez was convicted of second and fourth degree assault, in violation of double jeopardy. Consequently, we reverse his conviction for fourth degree assault and remand with instructions.

¶2 Villanueva-Gonzalez and M.G. were in a romantic relationship. On the night in question, Villanueva-Gonzalez returned home angry because M.G. had been out at a nightclub without him. He confronted M.G. and pulled her out of the room in which she was sitting. He head butted her, fracturing her nose in two places. Villanueva-Gonzalez then grabbed M.G. by the throat and held her against a piece of furniture.

¶3 The State charged Villanueva-Gonzalez with two counts of second degree assault. Count I was based on Villanueva-Gonzalez’s attempted strangulation of M.G. Villanueva-Gonzalez’s injury to M.G.’s nose was the basis for count II.

¶4 After a jury trial, the court instructed the jury as to second degree assault and the lesser included fourth degree assault for both counts I and II. The jury found VillanuevaGonzalez guilty of second degree assault for count II. It also found him guilty of the lesser included crime of fourth degree assault as to count I.

¶5 Villanueva-Gonzalez appeals.

DOUBLE JEOPARDY

¶6 Villanueva-Gonzalez argues that his convictions for second and fourth degree assault violated his right against double jeopardy. We agree.

¶7 Article I, section 9 of the Washington Constitution, the double jeopardy clause, guarantees that “[n]o person shall ... be twice put in jeopardy for the same offense.” It mirrors the protections offered by the federal *5constitutional protection against double jeopardy.2 “Double jeopardy principles protect a defendant from being convicted more than once under the same statute if the defendant commits only one unit of the crime.”3 “Where a defendant’s act supports charges under two criminal statutes, a court weighing a double jeopardy challenge must determine whether, in light of legislative intent, the charged crimes constitute the same offense.”4 “To determine if a defendant has been punished multiple times for the same offense, this court has traditionally applied the ‘same evidence’ test.”5 This test “mirrors the federal ‘same elements’ standard adopted in Blockburger v. United States.”6

¶8 Under this test, two convictions constitute the “same offense” for the purposes of double jeopardy if they are the same in law and in fact.7 Thus, if each conviction includes elements not included in the other or requires proof of a fact that the other does not, the offenses are different and the convictions may stand.8

¶9 For the first time on appeal, Villanueva-Gonzalez argues that his convictions for assault in the second and fourth degree have subjected him to double jeopardy. Even though this issue was not raised below, we consider it *6because it involves an alleged violation of VillanuevaGonzalez’s constitutional right against double jeopardy.9

¶10 Here, Villanueva-Gonzalez’s convictions violated double jeopardy. As a lesser included offense of second degree assault, fourth degree assault is the same in law as second degree assault.10 It requires proof that the defendant assaulted another, an element required by second degree assault.11

¶11 Villanueva-Gonzalez’s convictions were also the same in fact. The State alleged that VillanuevaGonzalez committed two separate assaults: grabbing of M.G.’s throat and head butting her. But these events were actions taken against the same victim within the same short time span. Because “assault” is not defined in terms of each physical act against a victim, Villanueva-Gonzalez’s actions constituted one single assault in fact. As the supreme court in State v. Tili stated:

[T]he assault statute does not define the specific unit of prosecution in terms of each physical act against a victim. Rather, the Legislature defined “assault” only as that occurring when an individual “assaults” another. A more extensive definition of “assault” is provided by the common law, which sets out many different acts as constituting “assault,” some of which do not even require touching. Consequently, the Legislature clearly has not defined “assault” as occurring upon any physical act.[12]

*7¶12 Here, the evidence to prove each charged crime was the assaultive acts committed against the victim. Because “assault” is not defined in terms of each separate physical act, the assaults here were the same in fact.13 Thus, it was a violation of double jeopardy to convict VillanuevaGonzalez of two different offenses that were the same in fact.

¶13 The State argues that Villanueva-Gonzalez’s rights against double jeopardy were not violated, but it applies the “unit of prosecution” test. This is the wrong inquiry. As our supreme court recognized in State v. Adel, the “same evidence” test, not the “unit of prosecution” test, applies “to a situation where a defendant has multiple convictions for violating several statutory provisions.”14 The “unit of prosecution” test is appropriate only where a defendant is “convicted for violating one statute multiple times.”15 Here, though Villanueva-Gonzalez was charged with two counts of second degree assault, the jury convicted him of one count of fourth degree assault and one count of second degree assault. Thus, the appropriate test to determine whether these convictions violated double jeopardy is the “same evidence” test, not the “unit of prosecution” test. Consequently, the State’s argument is not supported by controlling law.

¶14 The State also argues that Villanueva-Gonzalez’s actions of grabbing M.G.’s throat and head butting her constituted two separate assaults in fact. The State improperly relies on Till to support this argument. In Till, the court upheld the defendant’s convictions for three counts of rape. In doing so, it rejected Tili’s argument that “if he can be charged and convicted for three counts of first-degree rape based on three separate penetrations, then a defendant *8could also be charged and convicted for every punch thrown in a fistfight without violating double jeopardy.”16 As noted above, the supreme court in Tili discussed how assault, unlike rape, is not defined by every individual physical act.17 Thus, the State’s citation to Tili, rather than buttressing its argument, demonstrates why Villanueva-Gonzalez’s conviction violated double jeopardy.

¶15 Finally, the State submitted a statement of additional authorities, citing State v. Nysta.18 There, this court concluded that Nysta’s convictions for second degree rape and felony harassment did not violate the prohibition against double jeopardy.19 That case is unhelpful. The convictions here were for second and fourth degree assault, which fail to satisfy the same evidence test that we discussed in this opinion.

¶16 When a conviction violates double jeopardy principles, we must reverse and remand a sentence that contains convictions for the same offense with instructions to vacate the lesser punished crime.20 Here, the lesser punished crime was the fourth degree assault offense. Thus, the trial court should vacate the fourth degree assault conviction.

¶17 We reverse and remand with instructions to vacate only the fourth degree assault conviction. The second degree assault conviction remains undisturbed.
